soc/amd/common/vboot: Verify location of CBMEMC transfer buffer

Since we want to read the non-x86 CBMEMC from SMM we need to be stricter
on where we read from. This change forces the verstage binary and x86
code to agree on the CBMEMC transfer buffer location and size.

BUG=b:221231786
TEST=Boot guybrush and verify verstage transfer buffer still ends up in
cbmem
