I thought about that, but then we end up having to add a bunch more
checks in the code for all the cases where we just check for
CHIP_RAVEN today.  It also doesn't solve the fact that you can have
multiple apu flags set for a particular asic.  E.g., there are RAVEN
based RAVEN2 chips and PICASSO based RAVEN2 chips.  To account for all
of those we'd end up needing five new CHIP_ variants just for all of
the RAVEN chips which are pretty much all the same other than the
firmware they load.
