drm/plane-helper: Add a drm_plane_helper_atomic_check() helper
Provides a default plane state check handler for primary planes that are a
fullscreen scanout buffer and whose state scale and position can't change.
There are some drivers that duplicate this logic in their helpers, such as
simpledrm and ssd130x. Factor out this common code into a plane helper and
make drivers use it.
