Subject: drm/omap: remove omap_drm_win
Git-commit: 218ed5358a4045382674f8feeee0efb526f9431b
Patch-mainline: v4.13-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166

struct omap_drm_window is only used to pass plane setup data to
omap_framebuffer_update_scanout(). This can as well be accomplished by
just passing the DRM state.
