From: Kieran Bingham <kieran.bingham+renesas@xxxxxxxxxxxxxxxx> To support using endpoints in the V4L2 Async subdev framework, we need to be able to parse a fwnode for the device from the endpoint. To enable this, provide an alternative of_graph_get_remote_port_parent which walks up the port hierarchy without parsing the 'remote-endpoint' first. Using this new of_graph_get_port_parent() implementation we can then add the corresponding fwnode_graph_get_port_parent() call for use by the async framework.
