version 4:
fix null pointer issue while setting zpos in plane reset function

This patch replaces zpos property handling custom code in rcar DRM
driver with calls to generic DRM code.

Hi Benjamin,

(Trimming down the CC list of bit as most people are not interested in the
rcar-du-drm details)

I've rebased your zpos series on top of

	git://linuxtv.org/media_tree.git vsp1

that includes two patches for the rcar-du-drm driver that conflict with your
series. The branch will be pushed as-is to Linus in v4.8 by Mauro, and can
thus be merged by Dave in his tree. This patch is the result of the rebase.

I haven't added my Tested-by tag yet as patch 1/4 in your series causes issues
with rcar-du-drm. I'll retest the whole series when a fix will be available.
