freedreno/a6xx: Fix UBWC blockheight for RG8.
Using texturator on a P3A at 1024x1024, RG8 has log2w/h of 6x7 instead of R16I/UI's 6x8. The other blockw/h I verified other than cpp=1 (R8/R8I/R8UI didn't use UBWC) and 32 (would need a bigger type). Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/4931>
