src/device: Add option to look at revision in option roms
AMD's Family 17h SOCs have the same vendor and device IDs for
their graphics blocks, but need different video BIOSes. The
only difference is the revision number.
Add a Kconfig option that allows us to add the revision number
of the graphics device to the PCI option rom saved in CBFS.
Because searching CBFS takes a non-trivial amount of time,
only enable the option if it's needed. If it's not used, or
if nothing matches, the check will fall through and search for
an option rom with no version.
BUG=b:145817712
TEST=With surrounding patches, loads dali vbios
