The code in mrc_cache.c doesn't check for the presence of 'mrc.cache',
and just returns hardcoded value for he location of he MRC cache. This
becomes a problem when there is a CBFS file at the same location,
which can get overwritten. A CBFS file is created to cover this region
so that nothing can be added there.
This has the advantage of creating a build time error if another cbfs
file is hardcoded over the same region.
The default location of the MRC cache is also moved to 4G - 128K to
ensure that it defaults to something within CBFS.

The stage_cache_external_region() calculation is actually
dependennt on the properties of the chipset. The reason
is that certain regions within the SMRAM are used for
chipset-specific features. Therefore, provide an API
for abstracting the querying of subregions within
the SMRAM.
The 3 subregions introduced are:
SMM_SUBREGION_HANDLER - SMM handler area
SMM_SUBREGION_CACHE - SMM cache region
SMM_SUBREGION_CHIPSET - Chipset specific area.
The subregions can be queried using the newly
added smm_subregion() function.
Now stage_cache_external_region() uses smm_subregion()
to query the external stage cache in SMRAM, and this
patch also eliminates 2 separate implementations of
stage_cache_external_region() between romstage and
ramstage.

In the true spirit of separating components more strictly
and allowing to add new components to coreboot without touching
existing code, move Intel common code selection to the soc
Kconfig and out of src/soc/intel/common/Makefile.inc

This change switches all SOC vendors and southbridges
to be autoincluded by Makefile.inc, rather than having to be
mentioned explicitly in soc/Makefile.inc or in
soc/<vendor>/Makefile.inc.
This means, vendor and SOC directories are now "drop
in", e.g. be placed in the coreboot directory hierarchy
without having to modify any higher level coreboot files.
The long term plan is to enable out of tree components to be
built with a given coreboot version (given that the API did not
change).
