Convert the driver to use the DRM_BRIDGE_ATTACH_NO_CONNECTOR flag when attaching bridges. This modernizes the driver by delegating connector creation to the bridge subsystem through drm_bridge_connector_init() instead of manually searching for connectors created by the bridge. The custom tilcdc_encoder_find_connector() function is removed and replaced with the standard drm_bridge_connector infrastructure, which simplifies the code and aligns with current DRM bridge best practices. This change is safe as there are now no in-tree devicetrees that connect tilcdc to bridges which do not support the DRM_BRIDGE_ATTACH_NO_CONNECTOR flag.

Modifies the live device tree at early boot to convert the legacy
|
|
"ti,tilcdc,panel" devicetree node to the standard panel-dpi node.
|
|
This allows to maintain backward compatibility for boards which
|
|
were using the deprecated tilcdc_panel driver.
|
|
If you find "ti,tilcdc,panel"-string from your DTB, you probably
|
|
need this. Otherwise you do not.
