Claude review: drm/bridge: aux: Add drm_aux_bridge_register_from_node()

[Claude Code Review Bot <claude-review@example.com>]

Patch Review

Clean patch. The refactoring to make `drm_aux_bridge_register()` a wrapper around the new `_from_node()` variant is the right approach.

**Minor nit:** The kdoc on the original `drm_aux_bridge_register()` is updated to add `@np` but that parameter doesn't exist on the old function — the `@np` doc belongs only on the new `drm_aux_bridge_register_from_node()`. Looking more carefully:

```c
/**
 * drm_aux_bridge_register - Create a simple bridge device to link the chain
 * @parent: device instance providing this bridge
 * @np: device node pointer corresponding to this bridge instance
```

This kdoc block is placed on `drm_aux_bridge_register_from_node()` after the rename, so the function name in the doc comment (`drm_aux_bridge_register`) is now wrong — it should say `drm_aux_bridge_register_from_node`. The `@np` parameter description should also mention that NULL falls back to the parent device's of_node.
