Subject: drm/sun4i: Rename DE2 RGB format macros
Git-commit: cbd2b690a434766559eed943947f3ec533ccde9c
Patch-mainline: v4.16-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166

Current RGB formats macros are actually not specific to UI planes.
Rename it to something more universal and introduce shift macro.
