drm/exynos: add prepare and cleanup phases for planes
From: Gustavo Padovan <gustavo.padovan@collabora.co.uk> .prepare_plane() and .cleanup_plane() allows to perform extra operations before and after the update of planes. For FIMD for example this will be used to enable disable the shadow protection bit. Signed-off-by: Gustavo Padovan <gustavo.padovan@collabora.co.uk> Signed-off-by: Inki Dae <inki.dae@samsung.com>
