drm/bridge: add anx7625 DSI to DP bridge driver

Analogix ANX7625 SlimPort (Full-HD Transmitter)

-----------------------------------------------

The ANX7625 is DSI to DisplayPort bridge.

Required properties:

 - compatible		: "analogix,anx7625"

 - reg			: I2C address of the device

 - interrupt-parent	: Should be the phandle of the interrupt controller

			  that services interrupts for this device

 - interrupts		: Should contain the INTP interrupt

 - cbl_det-gpios	: Which GPIO to use for cable detection

 - power_en-gpios	: Which GPIO to use for power enable

 - reset_n-gpios	: Which GPIO to use for reset

 - ports		: Port 0 for DSI input, should be a reference to a

			  valid mipi_dsi_host device

Example:

	anx7625: anx7625@ee {

		compatible = "analogix,anx7625";

		reg = <0xee>;

		interrupt-parent = <&qup15>;

		interrupts = <2 IRQ_TYPE_LEVEL_LOW>;   /* INTP */

		cbl_det-gpio = <&qup15 1 GPIO_ACTIVE_HIGH>;

		power_en-gpio = <&pio 27 GPIO_ACTIVE_HIGH>;

		reset_n-gpio = <&pio 49 GPIO_ACTIVE_HIGH>;

		ports {

			#address-cells = <1>;

			#size-cells = <0>;

			port@0 {

				reg = <0>;

				anx7625_in: endpoint {

					remote-endpoint = <&dsi_out>;

				};

			};

		};

	};

	  the HDMI output of an application processor to MyDP

	  or DisplayPort.
