From: Dave Airlie <airlied@xxxxxxxxxx>
Rework the plane init calls to do the gen test one level higher.
Rework some of the plane helpers so they can live in new file,
there is still some scope to clean up the plane/fb interactions
later.
v2: drop atomic code back, rename file to Ville suggestions,
add header file.
