It rewrites the results of receive enable stored in the upper nvram
region, to avoid running receive enable again.
Some debug info is also printed about the self-refresh registers.
(Not enforcing a reset here, since 0 does not necessarily mean it's
not in self-refresh).

Previously the raminit failed on hot reset and to work around this
issue it unconditionally did a cold reset.
This has the following issues:
* it's slow;
* when the OS issues a hot reset some disk drives expect their 5V
power supply to remain on, which gets cut off by a cold reset,
causing data corruption.
To fix this some steps in raminit must be ommited on the reset path.
This includes receive enable calibration.
To achieve this it stores receive enable results in RTC nvram for them
to be rewritten on the resume path.
Note: The same thing needs to be done on the S3 resume path.
Calling a hot reset after raminit "outb(0x6, 0cf9)" works.

Fix-up for 696abfc
nb/intel/x4x: Fix and deflate `dimm_config` in raminit
It didn't fix the channel-number shifting issue as intended.
The channel index is either 0 or 1. DIMMs are counted from 0
to 3 where 0..1 covers channel 0, and 2..3 covers channel 1.
Since we have two DIMMs per channel, we have to multiply the
channel index by 2 (or shift it left by 1) to get the index
of the first DIMM in the channel. Finally, to get the offset
of a DIMM in the channel we take its index modulo 2 (again,
the number of DIMMs per channel).

By shifting the `chan` right instead of left, values were always taken
from the DIMMs of the first channel. The diff-stat also looks like an
improvement.

Previously, 0x0 was the value being used for an unpopulated dimm
on spd[62], however some DDR2 dimms have 0x0 as a valid value.
Now use 0xff which is an unused value even on DDR2/DDR3.

The values were obtained from vendor bios at runtime.
I am not 100% sure of the sequence required to initiate them,
but guessed from the gm45 code. There may be some status bytes
needed to be polled during the sequence that is missing,
but as I don't have bios writer's datasheet it's very hard
for me to know.

- Don't redefine D0F0_PCIEXBAR_LO, use the #define in x4x.h
- Move TPMBASE and TPM32() definitions into iomap.h
- Use "" style include for x4x.h in nortbridge files.
- Move includes of .h files out of x4x.h and into the c files that need
them.
- Protect function definitions in bootblock.
