[PATCH v10 11/17] drm/exynos: remove exported functions from exynos_drm_plane

From: Gustavo Padovan <gustavo.padovan@collabora.co.uk>

Now that no one is using the functions exported by exynos_drm_plane due
to the atomic conversion we can make remove some of the them or make them
static.

v2: remove unused exynos_drm_crtc

v3: fix checkpatch error (reported by Joonyoung)
