Subject: drm/armada: move colorkey properties into overlay plane state
Git-commit: c96103b6c49ff9a8710e580da72c0f116d24a76c
Patch-mainline: v4.19-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166
Move the overlay plane colorkey properties into the plane state,
keeping the existing driver behaviour to avoid breaking userspace.
