drm/rcar: plane: Remove redundant zpos initialisation

The rcar-du KMS driver will call drm_plane_create_zpos_property() with an
init value depending on the plane type.

Since the initial value wasn't carried over in the state, the driver had
to set it again in rcar_du_plane_reset() and rcar_du_vsp_plane_reset().
However, the helpers have been adjusted to set it properly at reset, so
this is not needed anymore.
