soc/amd/cezanne,common,picasso: use BERT region reserved by FSP driver
commit ce0e2a014009390c4527e064efb59260ef4d3a3b (drivers/intel/fsp2_0:
use FSP to allocate APEI BERT memory region) adds a mechanism to reserve
the BERT region inside the coreboot code, so we can get rid of the
workaround to reserve it in the FSP and return the location in a HOB.
mcfg->bert_size defaults to 0 which makes the FSP not generate the
corresponding HOB, but that field is planned to be removed at least on
Cezanne, so don't explicitly set it to 0.
BUG=b:169934025
TEST=BERT table that gets generated in a follow-up patch for Picasso
points to expected BERT region and Linux is able to access, decode and
display it.
