I'm fine with the zpos change, but I'd like to keep the omap_plane_state
around. It'll be empty after this patch, but we have a bunch of
properties we need to add. Some can be added as common DRM properties,
but perhaps not all. It's so much easier to handle those patches if the
plumbing is there already, instead of adding it back.
