CSI2 registers camera/sensor as v4l2 async sub device with fwnode is
remote endpoint and the camera/sensor register itself as v4l2 sub device
with fwnode is remote device as a result the match.fwnode should be
fwnode_graph_get_remote_port_parent and not
fwnode_graph_get_remote_endpoint.
This patch makes use of v4l2 helper function
v4l2_async_notifier_add_fwnode_remote_subdev() which uses
fwnode_graph_get_remote_port_parent as match.fwnode fixing the issue
of registering camera endpoint to the driver.
