Subject: [PATCH 2/6] dt-bindings: display: rockchip-dsi: add optional #phy-cells property

From: Heiko Stuebner <heiko.stuebner@...obroma-systems.com>

The Rockchip DSI controller on some SoCs also controls a bidrectional
dphy, which would be connected to an Image Signal Processor as a phy
in the rx configuration.

So allow a #phy-cells property for the dsi controller.
