This series builds upon the set of fixes previously submitted to move
Armada DRM closer to atomic modeset. We're nowhere near yet, but this
series helps to get us closer by unifying some of the differences
between the primary and overlay planes.
New features added allows userspace to disable the primary plane if
overlay is full screen and there's nothing obscuring the colorkey -
this saves having to fetch an entire buffer containing nothing but
colorkey when displaying full screen video.
