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 it late in post, then storing the
S3 volatile data to the region. Remove the hardcoded base address
that was missed in that commit.
To prepare for S3 support, split the region into subregions for
heap, AGESA's S3 volatile storage, and an MTRR save area.
