soc/amd/common/block/graphics: Don't add VBIOS to cbmem when using GOP 

pci_rom_ssdt reloads the oprom from cbfs. It then places it into cbmem
and writes the offsets as the ROM ACPI node. The GOP driver modifies the
VBIOS so we don't want to reread from cbfs. When using GOP we also pass
the offsets with the VFCT table.
