The hardware supports either size. Also add checks to ensure that only
these two sizes may be used for supplying a LUT.

Only tested on G84 and GK208. The GV100+ is entirely untested.
With the fixed modetest tool, setting ilut and olut sizes to different
quantities seems to work out OK, across a range of formats (XR24, XB30,
XB4H).
