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 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>
