[PATCH v4] dt-bindings: display: anx7814.txt: convert to yaml

[Ricardo Cañuelo]

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.

Changes in v4:
  - Make interrupts and gpios optional (Enric Balletbo)
  - Make hpd-gpios deprecated (Rob Herring)
  - Remove maxItems from dvdd10-supply

Changes in v3 (suggested by Sam Ravnborg):
  - Rename example node i2c0 to i2c.

Changes in v2 (suggested by Enric Balletbo):
  - File name change: use full compatible string.
  - Binding description removed.
  - #address-cells and #size-cells properties removed from ports node.
  - Example node renamed: anx7814 -> bridge.

Tested with:
make dt_binding_check ARCH=arm64 DT_SCHEMA_FILES=<.../analogix,anx7814.yaml>
make dtbs_check ARCH=arm64 DT_SCHEMA_FILES=<.../analogix,anx7814.yaml>

- - 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].
