Populate netdev of_node with pdev of_node so that the network device
inherits the device tree node information from the platform device and
its of_node is available in sysfs.

Without this, udev is unable to expose the OF_* properties (OF_NAME,
OF_FULLNAME, OF_COMPATIBLE, OF_ALIAS, etc.) for the network interface.
These properties are commonly used by udev rules and other userspace
tools for device identification and configuration.

You may need to use device_set_of_node_from_dev.
