Merge branch 'dpaa2-eth-of_node'

Ioana Ciornei says:

====================
dpaa2-eth: setup the of_node

This patch set allows DSA to work with a DPAA2 master device by setting
up the of_node to point to the corresponding MAC DTS node, so that
of_find_net_device_by_node() can find it.
As an added benefit, udev rules can now be used to create a naming
scheme based on the physical MAC.

The second patch renames the debugfs directory to use the DPNI name
instead of the netdev name, since the latter can be changed after probe
time.
