freedreno/a6xx: disable LRZ for z32
f6131d4ec7a had the side effect of enabling LRZ w/ 32b depth buffers. But there are some bugs with this, which aren't fully understood yet, so for now just skip LRZ w/ z32.. Fixes: f6131d4ec7a freedreno/a6xx: Clear z32 and separate stencil with blitter Signed-off-by: Rob Clark <robdclark@gmail.com>
