Now that we have the graph schema, convert the video-mux binding to DT
schema.

-Video Multiplexer
-=================
-
-Video multiplexers allow to select between multiple input ports. Video received
-on the active input port is passed through to the output port. Muxes described
-by this binding are controlled by a multiplexer controller that is described by
-the bindings in Documentation/devicetree/bindings/mux/mux-controller.txt
-
-Required properties:
-- compatible : should be "video-mux"
-- mux-controls : mux controller node to use for operating the mux
-- #address-cells: should be <1>
-- #size-cells: should be <0>
-- port@*: at least three port nodes containing endpoints connecting to the
- source and sink devices according to of_graph bindings. The last port is
- the output port, all others are inputs.
-
-Optionally, #address-cells, #size-cells, and port nodes can be grouped under a
-ports node as described in Documentation/devicetree/bindings/graph.txt.
-
-Example:
-
- mux: mux-controller {
- compatible = "gpio-mux";
- #mux-control-cells = <0>;
-
- mux-gpios = <&gpio1 15 GPIO_ACTIVE_HIGH>;
- };
-
- video-mux {
- compatible = "video-mux";
- mux-controls = <&mux>;
- #address-cells = <1>;
- #size-cells = <0>;
-
- port@0 {
- reg = <0>;
-
- mux_in0: endpoint {
- remote-endpoint = <&video_source0_out>;
- };
- };
-
- port@1 {
- reg = <1>;
-
- mux_in1: endpoint {
- remote-endpoint = <&video_source1_out>;
- };
- };
-
- port@2 {
- reg = <2>;
-
- mux_out: endpoint {
- remote-endpoint = <&capture_interface_in>;
- };
- };
- };
-};
