soc/amd/common/block/acpimmio: add Kconfig option for biosram accessors
The biosram accessor support in soc/amd/common/block/acpimmio/biosram.c
is only used on Stoneyridge and the old amd/southbridge code and not on
Picasso or Cezanne. It also only builds as a 32 bit binary and breaks
when trying to build as a 64 bit binary, since the size of an uintptr_t
is different on those two. There is no support for using the 32 bit
binaryPI with a 64 bit coreboot while there is code to use a 32 bit FSP
with 64 bit coreboot, so not building this for FSP-based SoC support
moves us one step closer to be able to build coreboot as 64 bit binary
for Picasso and Cezanne.
