Subject: [PATCH] freedreno, turnip: Disable 8bpp UBWC on a650

While it doesn't immediately hang like on a660, it seems to be buggy and
the blob disables it.

This fixes a bunch of r8_* dEQP-VK tests, which seem to pass
individually but don't work when run after other tests. For example this
fixes failures running dEQP-VK.pipeline.sampler.*.r8_uint*.
