[PATCH v2] add mdio bus support to miitool

[Sascha Hauer]

2nd version. This adds both the mdio buses and the phy devices
to the mdio_bus_type. This is in sync with Linux which also
adds the buses (for example i2c_adapter) and the devices (for example
i2c devices) to the same bus type. Linux uses a struct device_type
pointer in struct device to distinguish between both. As we do
not have this struct, we use the type_data field which has the
same purpose.
