soc/amd/*: Set AMD_FW_AB_POSITION to either 64 or 128 bytes
When CBFS verification is enabled, add amdfw_a/b.rom at offset 128 bytes
to account for CBFS file header with hash attribute. When CBFS
verification is disabled, add amdfw_a/b.rom at offset 64 bytes to
account for CBFS file header without hash attribute.
BUG=None
TEST=Build Skyrim, Myst BIOS images with and without CBFS verification
enabled.
