Commit Message

Kieran Bingham Jan. 14, 2021, 4:22 p.m. UTC 
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.
