drm: omapdrm: Add zpos property
Create a standard zpos property for every plane as an alias to the omapdrm-specific zorder property. Unlike the zorder property that has to be instantiated for both planes and CRTCs due to backward compatibility, the zpos property is only instantiated for planes. When userspace will have switched to the zpos property the zorder property will be removed.
