We are about to use vc4_plane_mode_set() in the async check path, but async check can decide that async update is not possible and force the driver to fallback to a sync update. All the checks that have been done on the plane state during async check stay valid, and checking it again is not necessary. Add a ->checked field to vc4_plane_state, and use it to track the status of the state (checked or not).
