net: fix circular dependency in of_mdio code
Commit 86f6cf4127 (net: of_mdio: add of_mdiobus_link_phydev()) introduced a circular dependency between libphy and of_mdio. depmod: ERROR: <modroot>/kernel/drivers/net/phy/libphy.ko in dependency cycle! depmod: ERROR: <modroot>/kernel/drivers/of/of_mdio.ko in dependency cycle! The problem is that of_mdio.c references &mdio_bus_type and libphy now references of_mdiobus_link_phydev. Fix this by not exporting of_mdiobus_link_phydev() from of_mdio.ko. Make it a static function in mdio_bus.c instead.
