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

We already have the plane pointer in before calling .update_plane() or
disable_plane() so pass it directly to those calls avoiding a new
conversion from zpos to struct exynos_drm_plane.

v2: don't remove check for suspended in FIMD (comment by Joonyoung)
