net: lan966x: add missing fwnode_handle_put() for ports node
[ 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.
