dt-bindings: display: anx7814.txt: convert to yaml

This converts the Analogix ANX7814 bridge DT binding to yaml. Port
definitions and descriptions were expanded, apart from that it's a
direct translation from the original binding.

-Analogix ANX7814 SlimPort (Full-HD Transmitter)
------------------------------------------------
-
-The ANX7814 is an ultra-low power Full-HD (1080p60) SlimPort transmitter
-designed for portable devices.
-
-Required properties:
-
- - compatible		: Must be one of:
-			  "analogix,anx7808"
-			  "analogix,anx7812"
-			  "analogix,anx7814"
-			  "analogix,anx7818"
- - reg			: I2C address of the device
- - interrupts		: Should contain the INTP interrupt
- - hpd-gpios		: Which GPIO to use for hpd
- - pd-gpios		: Which GPIO to use for power down
- - reset-gpios		: Which GPIO to use for reset
-
-Optional properties:
-
- - dvdd10-supply	: Regulator for 1.0V digital core power.
- - Video port for HDMI input, using the DT bindings defined in [1].

-Example:
-
-	anx7814: anx7814@38 {
-		compatible = "analogix,anx7814";
-		reg = <0x38>;
-		interrupt-parent = <&gpio0>;
-		interrupts = <99 IRQ_TYPE_LEVEL_LOW>;   /* INTP */
-		hpd-gpios = <&pio 36 GPIO_ACTIVE_HIGH>;
