This change allows Kconfig options ROM_SIZE and CBFS_SIZE to be
set with values that are not power of 2. The region programmed
as WB cacheable will include all of ROM_SIZE.
Side-effects to consider:
Memory region below flash may be tagged WRPROT cacheable. As an
example, with ROM_SIZE of 12 MB, CACHE_ROM_SIZE would be 16 MB.
Since this can overlap CAR, we add an explicit test and fail
on compile should this happen. To work around this problem, one
needs to use CACHE_ROM_SIZE_OVERRIDE in the mainboard Kconfig and
define a smaller region for WB cache.
With this change flash regions outside CBFS are also tagged WRPROT
cacheable. This covers IFD and ME and sections ChromeOS may use.

Here is a solution using the SSDT.
Unfortunately iasl does not resolve simple arithmetic at compile
time, so we can not use Add(DEFAULT_PMBASE, PCNTRL) in the
Processor statement.
This patch instead dynamically generates the processor statement.
I can't use the speedstep generate_cpu_entries() directly since the
cpu doesn't support speedstep.
For now the code is in the southbridge directory, but maybe it
should go into cpu/intel/ somewhere.
IIRC notebook cpus of the era can already have speedstep, so it
would probably be possible to pair the i82371eb with a
speedstep-capable cpu...
Also, I don't know if multiprocessor boards (abit bp6?) would need
to be handled differently.
Abuild-tested.
