[PATCH] net: of/phy: fix build error when phylib is built as a module

[BjÃrn Mork]

CONFIG_OF_MDIO is tristate and will be m if PHYLIB is m.  Use
IS_ENABLED macro to prevent build error:

 ERROR: "of_mdio_find_bus" [drivers/net/phy/mdio-mux.ko] undefined!

I wonder if this could be as banal as this?  Not even build tested...

Should be wrapped into commit 25106022 if it works, to ensure
bisectability.
