Retype the `pcie_port_coalesce` devicetree options and related variables
to better reflect their bivalue (boolean) nature.

The other two modes are not used by any mainboard, and the code seems to
be copied from older southbridges. As the code looks incorrect, drop it.

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.

The function `acpi_fill_fadt()` is based on that of sb/intel/bd82x6x.
Tested on an ASRock H81M-HDS and a Google Peppy board, both using Linux
4.9 with `acpi=strict`. No ACPI errors or warnings appear in the kernel
log. System reset, poweroff, and S3 suspend/resume continue to work.
General improvements
--------------------
- `fadt->preferred_pm_profile` is set based on the value of
`CONFIG_SYSTEM_TYPE_LAPTOP` instead of being hardcoded.
- Constants are used instead of magic values in more locations.
- `fadt->gpe0_blk`, `fadt->gpe0_blk_len`, and `fadt->x_gpe0_blk` are set
appropriately depending on whether the system uses Lynx Point LP or
not.
- Boards can indicate docking support in the FADT via the devicetree.
Changes to existing Lynx Point boards
-------------------------------------
- `header->asl_compiler_revision` changes from 1 to 0.
- `fadt->model` is left at 0 instead of being set to 1. This field is
only needed for ACPI 1.0 compatibility.
- `fadt->flush_size` and `fadt->flush_stride` are set to 0. This is
because their values are ignored, since `ACPI_FADT_WBINVD` is set in
`fadt->flags`.
- `fadt->duty_offset` is set to 0 instead of 1. None of the existing
boards indicate support for changing the processor duty cycle (as
`fadt->duty_width` is set to 0), so `fadt->duty_offset` does not
currently need to be set.
- Access sizes of registers are set.
- On mb/intel/baskingridge, the pmbase is now read using the common
function `get_pmbase()` instead of `pci_read_config16(...)`.
- On mb/intel/baskingridge, the value of `fadt->x_gpe0_blk.bit_width`
changes from 64 to 128. The correct value should be 128 (bits), to
match `fadt->gpe0_blk_len`, which is set to 16 (bytes).
- On Lynx Point LP systems, the unused extended address
`fadt->x_gpe0_blk` sets its address space ID to be consistent with
other unused extended addresses. Such a change should not alter the
interpretation of the registers as being unused. Why not set them all
to zero? Simply because the existing practice, in both coreboot and
some other vendors' firmware, has them set in such a case.

It encourages users from writing to the FSF without giving an address.
Linux also prefers to drop that and their checkpatch.pl (that we
imported) looks out for that.
This is the result of util/scripts/no-fsf-addresses.sh with no further
editing.

As per discussion with lawyers[tm], it's not a good idea to
shorten the license header too much - not for legal reasons
but because there are tools that look for them, and giving
them a standard pattern simplifies things.
However, we got confirmation that we don't have to update
every file ever added to coreboot whenever the FSF gets a
new lease, but can drop the address instead.
util/kconfig is excluded because that's imported code that
we may want to synchronize every now and then.

The PCIe root port has ASPM settings/workarounds that are only applied
based on the value of an undocumented bit in PCI config register 0x32C.
If that bit is not set for some reason then the settings are not applied.
This devicetree config option will force the ASPM settings for each port
based on the bit map.

This adds configuration of SerialIO devices in the Lynxpoint-LP
chipset. This includes DMA, I2C, SPI, UART, and SDIO controllers.
There is assorted magic setup necessary for the devices and
while it is similar for each device there are subtle differences
in some register settings.
These devices must be put into "ACPI Mode" in order to take
advantage of S0ix. When in ACPI mode the allocated PCI BARs
must be passed to ACPI so it can be relayed to the OS. When
the devices are in ACPI mode BAR0+BAR1 is saved into ACPI NVS
and then updated and returned when the OS calls _CRS.
Note that is is not entirely complete yet. We need to update
the IASL compiler in our build environment to support ACPI 5.0
in order to be able to pass the FixedDMA entries to the kernel.
There are also no ACPI methods defined yet to do D0->D3->D0
transitions for actually entering/exiting S0ix states.
This is hard to test right now because our kernel does not support
any of these devices in ACPI mode. I was able to build and test
the upstream bleeding-edge branch of the linux-pm git tree. With
that tree I was able to enumerate and load the driver for the
DesignWare I2C driver and attempt to probe the I2C bus -- although
there are no devices attatched.
I am also able to see the resources from ACPI in /proc/iomem get
reserved properly in the kernel.

This makes use of the new functions from pmutil.c that take
care of the differences between -H and -LP chipsets.
It also adds support for the LynxPoint-LP GPE0 register block
and the SMI/SCI routing differences.
The FADT is updated to report the new 256 byte GPE0 block on
wtm2/wtm2 boards which is too big for the 64bit X_GPE0 address
block so that part is zeroed to prevent IASL and the kernel
from complaining about a mismatch.
This was tested on WTM2. Unfortunately I am still unable to get an
SCI delivered from the EC but I suspect that is due to a magic
command needed to put the EC in ACPI mode. Instead I verified that
all of the power management and GPIO registers were set to expected
values.
I also tested transitions into S3 and S5 from both the kernel and
by pressing the power button at the developer mode screen and they
all function as expected.

The Haswell parts use a PCH code named Lynx Point (Series 8). Therefore,
the southbridge support is included as well. The basis for this code is
the Sandybridge code. Management Engine, IRQ routing, and ACPI still requires
more attention, but this is a good starting point.
This code partially gets up through the romstage just before training
memory on a Haswell reference board.
