Usually userspace don't want to have two overlay planes on the same zpos
so this change assign a different zpos for each plane. Before this change
a zpos of value zero was created for all planes so the userspace had to
set up the zpos of every plane it wanted to use.

Also all places that were storing zpos positions are now unsigned int.

drm/exynos: remove exynos_plane_dpms

The exynos_plane_dpms function handles enabled flag of exynos plane and
calls internal hw driver callback function for hw overlay on/off. But
it causes state disharmory problem currently and is will be obstacle to
apply atomic operation later to keep non-standard per-plane dpms state
like enabled flag.

Let's remove enabled flag, it just stop to recall internal callback
function but hw drivers can handle it properly. And call internal
callback function directly then we can remove unnecessary

Note that this patch removes a call to manager->ops->commit() in

fimd driver to set underlying timings and need only in full modeset
operations. For plane update only win_commit is needed.
