drm/tilcdc: Use devm_drm_of_get_bridge() helper

Browse Source 
Replace drm_of_find_panel_or_bridge() with the newer
devm_drm_of_get_bridge() helper which simplifies the code by:
- Automatically handling both panel and bridge cases internally
- Managing the panel-to-bridge conversion when needed
- Using devres for resource management, eliminating manual cleanup

This removes the need for explicit panel-to-bridge conversion via
devm_drm_panel_bridge_add_typed() and the associated error handling path.
