soc/amd: factor out acpi_soc_get_bert_region to amd/common

This also adds BERT table gerenation support for Cezanne, but since the
functionality to populate the BERT memory region isn't implemented yet,
this won't result in a BERT table being generated on Cezanne, since
bert_generate_ssdt will always return false there.

TEST=BERT ACPI table generation still works on AMD/Mandolin
