soc/amd/picasso/graphics: use RAVEN2_VBIOS_REV with RAVEN2_VBIOS_VID_DID

In order for the code to find the correct VBIOS file in CBFS, remap the
revision ID in the RAVEN2_VBIOS_VID_DID case to the one that matches the
CBFS file name. This will make the code work as expected on devices with
the PCI ID RAVEN2_VBIOS_VID_DID and a revision != RAVEN2_VBIOS_REV.
