freedreno/a6xx: Fix MSAA clear
We need to do MSAA clear on the 3d pipe, it seems to not work out
properly on 2d pipe (at least for 4x MSAA and heights that are not
multiple of 16).
This matches what blob and tu seem to do. Fixes the following with
DEQP_CONFIG=rgba8888d24s8ms4
dEQP-GLES31.functional.primitive_bounding_box.depth.builtin_depth.per_primitive_bbox_equal
dEQP-GLES31.functional.primitive_bounding_box.depth.builtin_depth.per_primitive_bbox_larger
dEQP-GLES31.functional.primitive_bounding_box.depth.user_defined_depth.per_primitive_bbox_equal
dEQP-GLES31.functional.primitive_bounding_box.depth.user_defined_depth.per_primitive_bbox_larger
