net: lan966x: add missing fwnode_handle_put() for ports node
Since the "ethernet-ports" node is retrieved using device_get_named_child_node(), it should be release after using it. Add missing fwnode_handle_put() and move the code that retrieved the node from device-tree to avoid complicated handling in case of error.
