The node pointer in question is not a child node, but the node assigned
to the port device itself, so we should not be using
devm_fwnode_get_gpiod_from_child() [that is going away], but standard
devm_gpiod_get().
To maintain the previous labeling we use gpiod_set_consumer_name() after
we acquire the GPIO.
