Add explicit CBMEM_STAGE_CACHE option. Rename
CACHE_RELOCATED_RAMSTAGE_OUTSIDE_CBMEM to TSEG_STAGE_CACHE.
Platforms with SMM_TSEG=y always need to implement
stage_cache_external_region(). It is allowed to return with a
region of size 0 to effectively disable the cache.
There are no provisions in Kconfig to degrade from
TSEG_STAGE_CACHE to CBMEM_STAGE_CACHE.
As a security measure CBMEM_STAGE_CACHE default is changed to
disabled. AGESA platforms without TSEG will experience slower
S3 resume speed unless they explicitly select the option.

This patch adds a few southbridge calls needed for parallel MP init.
Moves the smm_relocate() function to smm/gen1/smi.h, since that is
where this function is defined now.
Tested on Thinkpad X220, shaves off ~30ms on a 2 core, 4 threads CPU.

Intel pineview has the same alternative SMRR MSR and
IA32_FEATURE_CONTROL enable bit as core2 CPUs so properly check for
that before enabling this feature.
This also exposes a function to fetch whether alternative SMRR MSR's
ought to be used.

Its spreading copies got out of sync. And as it is not a standard header
but used in commonlib code, it belongs into commonlib. While we are at
it, always include it via GCC's `-include` switch.
Some Windows and BSD quirk handling went into the util copies. We always
guard from redefinitions now to prevent further issues.

As per internal discussion, there's no "ChromiumOS Authors" that's
meaningful outside the Chromium OS project, so change everything to the
contemporary "Google LLC."
While at it, also ensure consistency in the LLC variants (exactly one
trailing period).
"Google Inc" does not need to be touched, so leave them alone.

This makes i82801ix use the common smm southbridge code to set up smm
relocation and smi handler setup. This is needed in this change for the
the smm relocation code relies on some southbridge functions provided
in the common code. Some of the old code is kept for the Q35 qemu
target.
This also caches the TSEG region and therefore increases MTRR usage a
little in some cases.
Currently SMRR msr's are not set on model_1067x and model_6fx since this needs
the MSRR enable bit and lock set in IA32_FEATURE_CONTROL. This will be handled
properly in the subsequent parallel mp init patchset.
Tested on Thinkpad X200: boots and going to and resuming from S3 still
works fine.

TSEG is not accessible in ring 0 after it is locked in ramstage, in
contrast with cbmem which remains accessible. Assuming SMM does not
touch the cache this is a good region to cache stages.
The code is mostly copied from src/cpu/intel/haswell.
TESTED on Thinkpad X220: on a cold boot the stage cache gets created
and on S3 the cached ramstage gets properly used.

An epic battle to fix Nehalem finally ended when we found an odd mask
set in SMRR. This was caused by a wrong calculation of TSEG size. It
was assumed that TSEG spans the whole space between TSEG base
and GTT. This is wrong as TSEG base might have been aligned down.
TEST: On X201, copied 1GiB from usb key to sd-card and verified.
