[PATCH 7/9] drm/exynos: use drm atomic state directly

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

For some fields the use struct exynos_drm_plane filled with data from the plane state just creates a source of duplicated information and overhead. Here we change the crtc drivers to access the plane state directly simplifying the code by not relying on a exynos internal struct.
