Use the device-managed variant for the allocating the MDIO bus. This
cleans-up the code a little on the remove and error paths.

The MACB driver embeds an MDIO bus controller and for this reason there
was no need for an MDIO sub-node present to contain the PHY nodes. Adding
MDIO devies directly under an Ethernet node is deprecated, so an MDIO node
is included to contain of the PHY nodes (and other MDIO devices' nodes).

The MACB embeds an MDIO bus controller. For this reason, the PHY nodes
were represented as sub-nodes in the MACB node. Generally, the
Ethernet controller is different than the MDIO controller, so the PHYs
are probed by a separate MDIO driver. Since adding the PHY nodes directly
under the ETH node became deprecated, we adjust the MACB driver to look
for an MDIO node and register the subnode MDIO devices.
