[PATCH 2/2] net: stmmac: Populate netdev of_node

[Primoz Fiser]

Populate netdev of_node with device of_node so that the network device
inherits the device tree node information in case of platform device.
On the other hand, when stmmac_dvr_probe() is called from pci device,
of_node will be NULL preserving current behavior.

With this in place, when initiated from platform device, udev will be
able to export 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.
