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.

You should probably add a fixes tag to this:
Fixes: db8bcaad5393 ("net: lan966x: add the basic lan966x driver")

Other than that the patch itself looks good to me.
