Subject: [PATCH net-next] net: ti: icssg_prueth: populate netdev of_node

Allow of_find_net_device_by_node() to find icssg_prueth ports and make
the individual ports' of_nodes available in sysfs.

Tested on a TI AM64x SoC. I don't have a device using the icssg_prueth_sr1
variant of the driver, but as this part of icssg_prueth.c and
icssg_prueth_sr1.c is identical, it seems like a good idea to make the
same change in both variants.
