Since commit 2fc4d838aa ("drm: rcar: use generic code for managing
zpos plane property") the rcar-du driver stores the plane zpos in the
drm_plane_state structure. The commit however forgot to remove the zpos
field from the rcar_du_vsp_plane_state structure. Remove it.

On Gen3 platforms planes are managed by the external VSP compositor on
behalf of DRM/KMS. If VSP compositor support is not enabled in the DU
driver, the VSP initialization stub routine is called. Return an error
from that stub to fail explicitly, otherwise the device won't be usable
and the driver will crash.

On R-Car Gen3 SoCs the DU lost its ability to access memory directly and
needs to work in conjunction with the VSP to do so. This commit handles
the VSP internally to hide it from the user.
