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
exynos_plane_dpms function

Split update plane in two parts, an initial check part that can fail
and the update part that can't fail.
This is a important step for the upcoming atomic modesetting support.

We can safely use the exynos_update_plane() to update the plane
framebuffer for both the overlay and primary planes.
Note that this patch removes a call to manager->ops->commit() in
exynos_drm_crtc_mode_set_commit(). The commit() call is used only by the
fimd driver to set underlying timings and need only in full modeset
operations. For plane update only win_commit is needed.

It's doing nothing but calling exynos_crtc->ops->win_commit(), so let's
call this directly to avoid extra layers of abstraction.

The patch replaces legacy functions
drm_plane_init() / drm_crtc_init() with
drm_universal_plane_init() and drm_crtc_init_with_planes().
It allows to replace fake primary plane with the real one.
Additionally the patch leaves cleanup of crtcs to core,
this way planes and crtcs are cleaned in correct order.

Change all instances of possible_crtcs in the exynos drm driver to be
unsigned long. This matches the type used in the drm layer.

The plane enable/disable can control only a power of plane, so they will
be helpful to handle planes with dpms.

The exynos drm driver used a specific ioctl - DRM_EXYNOS_PLANE_SET_ZPOS
to set zpos of plane. It can be substitute to property of plane. This
patch adds a property for plane zpos and removes
DRM_EXYNOS_PLANE_SET_ZPOS ioctl.

There is no any reason to update overlay at crtc directly because the
crtc uses plane. Move its code to plane and call proper functions of
plane from crtc.

The exynos fimd supports 5 window overlays. Only one window overlay of
fimd is used by the crtc, so we need plane feature to use the rest
window overlays.
This creates one ioctl exynos specific - DRM_EXYNOS_PLANE_SET_ZPOS, it
is the ioctl to decide for user to assign which window overlay.
