[PATCH 1/4] drm: Keep a copy of last plane coordinates

[ville.syrjala@xxxxxxxxxxxxxxx]

From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx>

If the update_plane() operation succeeds, make a copy of the requested
src and crtc coordinates, so that the the plane may be reclipped if the
display mode changed later.
