media: Revert "media: v4l2-fwnode: Add a convenience function for registering subdevs with notifiers"
The users of v4l2_async_register_fwnode_subdev() have switched to parsing their endpoints and setting up async sub-device lists in their notifiers locally, without using the endpoint parsing callbacks. There are no more users of v4l2_async_register_fwnode_subdev() so this convenience function can be removed. This reverts commit 1634f0eded87d1f150e823fa56cd782ea0775eb2.
