Command timing is the absolute value of the most negative `pi_coding`
value across all ranks, or zero if there are no negative values. Use the
MAX() macro to ease proving that `cmd_delay` can never be negative, and
then drop the always-false underflow check.
The variable type for `cmd_delay` still needs to be signed because of
the comparisons with `pi_coding`, which is a signed value. Using an
unsigned type would result in undefined and also undesired behavior.

Clock is a differential signal and propagates faster than command and
control, therefore its timing needs to be offset with `pi_code_offset`.
It is also a periodic signal, so it can safely wrap around.
To avoid potential undefined behavior, make `clk_delay` signed. It makes
no difference with valid values, because the initial value can be proven
to never be negative and `pi_code_offset` is always positive. With this
change, it is possible to add an underflow check, for additional sanity.

Commit 7584e550cc (nb/intel/sandybridge: Clean up program_timings)
introduced this condition along with a comment that says the opposite.
Command and clock timings always need to be computed, so drop both the
nonsensical condition and the equally-worthless corresponding comment.

To allow adjusting the phase shift of the various I/O signals, the
memory controller contains several PIs (Phase Interpolators). These
devices subdivide a QCLK (quarter of a clock cycle) in 64 `ticks`,
and the desired phase shift is specified in a register. For shifts
larger than one QCLK, there are `logic delay` registers, which allow
shifting a whole number of QCLKs in addition to the PI phase shift.
The number of PI ticks in a QCLK is often used in raminit calculations.
Define the `QCLK_PI` macro and use it in place of magic numbers. In
addition, add macros for other commonly-used values that use `QCLK_PI`
to avoid unnecessarily repeating `2 * QCLK_PI`, such as `CCC_MAX_PI`.

Commit 7f1363d9b4 (nb/intel/sandybridge: Program MR2 shadow register)
has a bug where the system locks up and power cycles when booting Linux,
but is still able to pass memtest86+ with flying colors. The issue will
occur when the following conditions are true:
- CPU is Ivy Bridge
- Memory speed is not greater than 1066 MHz (DDR3-2133 or slower)
- System contains dual-rank DIMMs
- The second rank of the dual-rank DIMMs is mirrored
- All DIMMs support Extended Temperature Range
- At least one of the DIMMs does not support Auto Self-Refresh
If all of these conditions are met, the final value of the MR2 Shadow
registers configures the memory controller to issue a MRS command to
update MR2 before entering self-refresh mode, but indicates that rank
mirroring is not required (the first rank on a DIMM is never mirrored).
Before the memory controller enters self-refresh, it sends MRS commands
to all ranks to update MR2, but the missing address and bank mirroring
means DRAM chips on mirrored ranks instead clobber MR1 with junk data.
With garbage in MR1, the mirrored ranks no longer function properly,
which ultimately leads to all hell breaking loose (undefined behavior).
The condition is backwards, since only odd ranks can be mirrored. To
avoid this problem completely, simply remove the condition. The final
register value will still be correct, since the bits are always ORed.
Tested on Asus P8Z77-V LX2, fixes booting Linux with dual-rank DIMMs.

In order to run a write leveling test, one needs to unset the Qoff bit
in MR1, then run the test, and finally set Qoff again. The current IOSAV
sequence uses two subsequences to perform the test, while the other two
are unused. It is possible to perform the two necessary MR1 updates in
the same sequence, which can potentially improve runtime (not measured).
Since `write_mrreg` is no longer used, it is necessary to handle address
mirroring explicitly. This can be accomplished with the recently-added
`ddr3_mirror_mrreg` function, which is also used in `write_mrreg`.

Write training needs to update mode register 1, but `write_mrreg` will
clobber the IOSAV sequence. Reference code uses one four-subsequence to
unset Qoff in MR1, run the test, and finally set Qoff again. This will
be implemented in future changes, and will use the newly-added helper.

To replace the register writes with assignments to struct fields, we
would need to have the values as parameters of a single macro. So,
split the raw value of `IOSAV_n_SP_CMD_CTRL_ch` in two parts. Note that
the single command that sets bit 17 is likely wrong, but it will be
fixed after refactoring. For now, we'll treat it as part of `ranksel`.
Move the parameters of `ADDR_UPDATE` into the top-level IOSAV macro.
Hopefully, this will be enough to replace the underlying implementation.

We only write to the IOSAV LFSR registers twice, but we do so between
the writes to the other four IOSAV per-subsequence registers. Since we
know that the IOSAV is sleeping when we program the subsequences, we
might as well do the two oddball LFSR register writes after we have
programmed the always-written-to group of four registers. That way,
subsequent changes can reproducibly replace the four writes with a
single macro.

It is not necessary to pass its value around various function calls.
Move it closer to where it is actually used, so as to make it static.
Also, use config_of_soc and flip the branches of the first conditional.
Tested on Asus P8Z77-V LX2, still boots.

Some commands, like ZQCS and ZQCL, use the same macro. This is because
they differ in things outside of the IOSAV_SP_CMD_CTRL registers. Also,
correct a comment that does not concur with the actual command in use.
With BUILD_TIMELESS=1, the binary of ASUS P8Z77-V LX2 remains identical.

This register is specific to Ivy Bridge. This changes the binary because
the operations get reordered, but it is equivalent.

Header files are supposed to not make allocations from .bss. Builds
fail if said file is included multiple times. To prevent this from
happening, move the definitions to a C file.
Also, rename raminit_patterns to raminit_tables. This is because more
tables that are not patterns will be added here in subsequent changes.

It does not make sense to disable an optimization that was not enabled
before, especially if that optimization only applies to Ivy Bridge.
Tested, still boots and can suspend correctly with:
- Asus P8Z77-V LX2 with i5-3330 and Windows 10
- Gigabyte GA-H61MA-D3V with i5-2400 and Arch Linux

They're listed in AUTHORS and often incorrect anyway, for example:
- What's a "Copyright $year-present"?
- Which incarnation of Google (Inc, LLC, ...) is the current
copyright holder?
- People sometimes have their editor auto-add themselves to files even
though they only deleted stuff
- Or they let the editor automatically update the copyright year,
because why not?
- Who is the copyright holder "The coreboot project Authors"?
- Or "Generated Code"?
Sidestep all these issues by simply not putting these notices in
individual files, let's list all copyright holders in AUTHORS instead
and use the git history to deal with the rest.
