freedreno/a6xx: disable UBWC for some formats

Browse source 
An older blob claims to support UBWC w/ r32ui an r32i, but not r32f.
Results from deqp indicate that it doesn't work with r32ui and r32i.

This *could* also just mean that use as "IBO" (image) is more limited
than as texture, although blob also doesn't seem to bother to try to use
UBWC with images at all, so hard to know for sure.
