Biju Das April 11, 2023, 11:42 a.m. UTC 
Add RCar DU vsp lib support by moving rcar_du_vsp_disable()
to the lib file so that same function can be used by both
RCar and RZ/G2L DU VSP drivers.

Signed-off-by: Biju Das <biju.das.jz@bp.renesas.com>

v6->v7:
 * Rebased to drm-tip.
v1->v6:
 * Rebased on drm-misc-next and DU-next.
v1:
 * Created the lib suggested by Laurent.
