freedreno/a6xx: Align lrz height to 32

Browse source 
Emperically this seems to be required when doing a linear clear of the
tiled LRZ buffer (because height needs to match aligned height for a
linear clear to dtrt).

Issue could be reproduced with nolrzfc and:

  glmark2 -s 1472x920 --visual-config samples=2 -b terrain

Closes: https://gitlab.freedesktop.org/mesa/mesa/-/issues/12336
Fixes: a127a78548 ("freedreno: Re-enable LRZ for a7xx")
Signed-off-by: Rob Clark <robdclark@chromium.org>
