Subject[PATCH 2/3] drm: rcar-du: Convert to the new VSP atomic API
Date
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.
