amdblocks/acpimmio: Unify BIOSRAM usage
All AMD CPU families supported in coreboot have BIOSRAM space. Looking at
the source code, every family could have the same API to save and restore
cbmem top or UMA base and size.
Unify BIOSRAM layout and add implementation for cbmem top and UMA storing.
Also replace the existing implementation of cbmem top and UMA with the
BIOSRAM access.
TEST=boot PC Engines apu1 and apu2
