Claude review: dt-bindings: display: panel: Add Chipone ICNA 35xx OLED driver bindings

Patch Review

This patch adds the YAML DT binding for `chipone,icna35xx.yaml`.

**Generally looks good.** The binding correctly uses the two-level compatible scheme (board-specific + chip-generic fallback). A few minor observations:

1. **Non-standard supply names lack descriptions.** `disp-supply` and `blvdd-supply` are not common names. While `vdd`, `vddio`, and `vci` are well-known, these two would benefit from brief descriptions explaining what they power:

```yaml
  disp-supply: true
  blvdd-supply: true
```

Consider adding something like:
```yaml
  disp-supply:
    description: Display bias voltage supply
  blvdd-supply:
    description: Backlight LED voltage supply
```

2. The example is clean and follows conventions. The `port` property is optional, which is fine.

No blocking issues.
