[PATCH 0/3] media: v4l: async: add helper API v4l2_async_pad_init_and_register_subdev()

[Frank Li]

Add the helper API v4l2_async_pad_init_and_register_subdev(), which
combines media_entity_pads_init(), v4l2_subdev_init_finalize(), and
v4l2_async_register_subdev() into a single call.

Reduce code duplication and simplify error handling in drivers.

Only change dwc and cdns. If agree add API, more driver can be simplified.
