i915: make is_mtl a special case for bo cache
i915 kmd has a special case for MTL in shmem_object_init:
if (HAS_LLC(i915) || (GRAPHICS_VER_FULL(i915) >= IP_VER(12, 70)))
cache_level = I915_CACHE_LLC;
Meanwhile, its i915_gem_object_pin_to_display_plane has:
ret = i915_gem_object_set_cache_level(obj,
HAS_WT(i915) ?
I915_CACHE_WT : I915_CACHE_NONE);
Let's report GBM_BO_MAP_CACHE_CACHED on MTL unless BO_USE_SCANOUT is
set.
