Claude review: dt-bindings: display: bridge: Add ITE IT6162 MIPI DSI to HDMI bridge

Patch Review

The binding looks reasonable overall.

**Minor issues:**

1. **Only `port@1` is required, not `port@0`**: This is unusual — typically `port@0` would be the primary/required port, with `port@1` optional for dual-link mode. If single-DSI mode uses port@0 only, then `port@0` should be required and `port@1` optional. If the chip truly requires the second port at minimum, this should be explained in the description.

```yaml
    required:
      - port@1
```

2. **Missing `port@3` (HDMI output) from required**: An HDMI bridge without a required output port seems wrong. Most bridge bindings require the output port. Consider whether `port@3` should also be listed in the ports `required` section.

3. **No `additionalProperties: false`** on the `ports` node itself — only on port@0 and port@1 endpoints. This is minor but could allow unexpected properties in the ports container.
