dt-bindings: display: bridge: renesas,dsi-csi2-tx: Allow panel@ subnode
This controller can have both bridges and panels connected to it. In
order to describe panels properly in DT, pull in dsi-controller.yaml
and disallow only unevaluatedProperties, because the panel node is
optional. Include example binding with panel.
