[PATCH v2 net-next 3/5] net: phy: move (of_)mdio_find_bus to mdio_bus_provider.c

[Heiner Kallweit <hkallweit1@gmail.com>]

Functionality outside libphy shouldn't access mdio_bus_class directly.
So move both functions to the provider side. This is a step towards
making mdio_bus_class private to libphy.
