nv50: regenerate rnndb headers

nv50: regenerate rnndb headers

The headers hadn't been regenerated in a long time, and there were a few
minor divergences. Among other things, rnndb has changed naming to
G80/etc, for now I've not tackled switching that over and manually
replaced the nvidia codenames back to the chip ids. However no other
modifications of the headergen'd headers was done.
