The firmware node associated with the phylink instance might differ from the device firmware node passed in phylink_config as such device can reference the parent switch or other platform peripherals. Some function might need to reference this firmware node after phylink_create so add a dedicated fwnode entry in phylink internal struct and save it on phylink_create().
