Subject: [PATCH v2 1/3] drm/sun4i: Unify sun8i_*_layer structs
From: Ondrej Jirman <megi@....cz>
These structs are identical, use a single struct to represent private
data for the DRM plane. This is a preparation for configuring layer
routing from the CRTC (mixer) instead of current approach of setting
up routing from individual layer's atomic_update callback.
