[ Upstream commit 925f3deb45df73173a33e1e81db77575f4ffde39 ]
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.
