Series drm/i915: Migrate memory to SMEM when imported cross-device (v8) | expand

Whenever we had a user object (n_placements > 0), we were ignoring
obj->mm.region and always putting obj->placements[0] as the requested
region.  For LMEM+SMEM objects, this was causing them to get shoved into
LMEM on every i915_ttm_get_pages() even when SMEM was requested by, say,
i915_gem_object_migrate().
