soc/amd/picasso/graphics: implement map_oprom_vendev_rev
Picasso, Dali, and Pollock iGPU share the same PCI device ID, but need
different video BIOSes. This checks the vendor & device IDs along with
the revision and selects the correct video BIOS to use.
Also add the second VGA BIOS for Raven2-based SoCs and change all VGA
BIOS IDs to the format including the revision number.
Since SeaBIOS still expects the CBFS file name without the revision ID,
it won't find the VBIOS any more. As a temporary workaround add the
VBIOS for the silicon it will run on as VGA_BIOS_DGPU_*.
