netdev/of/phy: MDIO bus multiplexer support.

v2: Update bindings to use "reg" and "mdio-parent-bus" insutead of
    "cell-index" and "parent-bus"

v1:

We have several different boards with a multiplexer in the MDIO bus.
There is an MDIO bus controller connected to a switching device with
several child MDIO busses.

Everything is wired up using device tree bindings.

 1/3 - New of_mdio_find_bus() function used to help configuring the
       driver topology.

 2/3 - MDIO bus multiplexer framework.

 3/3 - A driver for a GPIO controlled multiplexer.


David Daney (3):
  netdev/of/phy: New function: of_mdio_find_bus().
  netdev/of/phy: Add MDIO bus multiplexer support.
  netdev/of/phy: Add MDIO bus multiplexer driven by GPIO lines.
