Couple of additional nits that you may or may not incorporate:

It would be cool if we could stop adding uppercase hex outside preprocessor
defines..

Rob, I'll be looking into reworking these into dynamic tables.. would you
be okay with two more additions (A730, A740) on top of this before I do that?
The number of these funcs has risen quite a bit and we're abusing the fact
that so far there's a 1-1 mapping of SoC-Adreno (at the current state of
mainline, not in general)..

Also something I'll be looking into in the near future..

I think changing the is_adreno_... to switch statements with a gpu_model
var would make it easier to read.. Should I also rework that?
