ABGR8888 is currently only honoured: - on VLV/CHV in sprite planes - on SKL+ for primary and sprite planes so only allow it for those platforms. Note that we only support ARGB8888/ABGR8888 on the primary plane for SKL/BXT because we have in line of sight the pipe bottom color on those platforms and because the primary plane programming on VLV/CHV doesn't anything different for those formats today. v2: Fix the logic to forbid the creation ABGR2101010 fbs (Ville) v3: Still allow the creation of ARGB8888 fbs now that cursor planes use real fb objects (found by PRTS).
