************ fix this up     soc/amd/common: Define regions in AGESA cbmem

In 6c747068 "amd/stoneyridge: Put AGESA heap into cbmem" the
AGESA heap was moved completely into cbmem.  This was a departure
from the "late cbmem init" method of adding late in post, then
storing the S3 volatile data to the region.

To prepare for S3 support, split the region into subregions for
heap, AGESAs S3 volatile storage, and an MTRR save area.
