I'd probably move the gen11+ check here too.
Starting to wonder if we shouldn't just stuff a few plane
masks into the device info (and replace all num_sprites
stuff with those).
Anyways, looks reasonable:

Also wondering what happened to some of the stuff I did to these
functions... Oh right, it was all part of some colorkey stuff
which by now needs to rebased.
