drm: Fix plane type uabi breakage
Turns out assuming that only stuff in uabi is uabi is a bit naive, and we have a bunch of properties for which the enum values are placed in random headers. A proper fix would be to split out uapi include headers, but meanwhile sprinkle at least some warning over them.
