dt-bindings: media: Convert video-mux to DT schema

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>;
};
};
};
};
