The hardware supports either size. Also add checks to ensure that only
these two sizes may be used for supplying a LUT.
Finally, experimental evidence suggests you can't mix sizes for degamma
and gamma. Disallow this as well.

Note that all the gv100+ changes are purely speculative.
Tested on a GK208 with 8- and 10-bpc formats (but still 8bpc output).
This is on top of the patches which I've sent in the past. You'll end up
with some conflicts, I suspect, but I can't rebase easily on your changes
since they're not in a linux tree.
