Merge branch 'mdio-nodes'

Ioana Ciornei says:

====================
net: mdio: setup both fwnode and of_node

The first patch in this series fixes a bug introduced by mistake in the
previous ACPI MDIO patch set.

The next two patches are adding a new helper which takes a device and a
fwnode_handle and populates both the of_node and fwnode so that we make
sure that a bug like this does not happen anymore.
Also, the new helper is used in the MDIO area.
