drm: rcar: use generic code for managing zpos plane property

Browse Source 
version 6:
rebased patch on top rcar-du changes for zpos

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.
