[Mesa-dev] [PATCH v3 05/25] panfrost: Convert ctx->{scratchpad, tiler_heap, tiler_dummy} to plain BOs

[Boris Brezillon]

ctx->{scratchpad,tiler_heap,tiler_dummy} are allocated using
panfrost_drm_allocate_slab() but they never any of the SLAB-based
allocation logic. Let's convert those fields to plain BOs.
