As a follow up of my atomic series I started cleaning up exynos drm a bit more
and right now I'm removing most of struct exynos_drm_plane. Most of the plane
information there is also present in plane->state thus I'm basically removing
all the duplicated information there.
That said, I think we avoid creating exynos_drm_plane_config and stuff
everything directly in struct exynos_drm_plane, it will be quite small and
easier to manipulate.
