[media] adv7604: Add endpoint properties to DT bindings
Add support for the hsync-active, vsync-active and pclk-sample properties to the DT bindings and control BT.656 mode implicitly.

- reset-gpios: Reference to the GPIO connected to the device's reset pin.
+Optional Endpoint Properties:
+
+ The following three properties are defined in video-interfaces.txt and are
+ valid for source endpoints only.
+
+ - hsync-active: Horizontal synchronization polarity. Defaults to active low.
+ - vsync-active: Vertical synchronization polarity. Defaults to active low.
+ - pclk-sample: Pixel clock polarity. Defaults to output on the falling edge.
+
+ If none of hsync-active, vsync-active and pclk-sample is specified the
+ endpoint will use embedded BT.656 synchronization.
