net: davinci_mdio: Use of_mdiobus_register()

of_mdiobus_register() calls mdiobus_register() internally, so the functionality is preserved. However, by calling the of_ variant, phy nodes can be augmented with extra information.

Are there any non Device Tree aware platforms using this driver? of_mdiobus_register() is an empty stub returning -ENOSYS when CONFIG_OF is not set, maybe we should make it return mdiobus_register() instead...
