The configuration API between the VSP and the DU has been updated to provide finer grain control over modesetting, and enablement. Split rcar_du_vsp_enable() into rcar_du_vsp_modeset() and rcar_du_vsp_enable() accordingly, and update each function to use the new VSP API. There are no further users of the deprecated vsp1_du_setup_lif() which can now be removed.
