net: of_mdio: use int type for address variable

Use int rather than u32 to fix the following warning:

drivers/of/of_mdio.c:147 of_mdiobus_register() warn: unsigned 'addr' is never less than zero.

David,

this patch and the next one fix warnings and build breakage reported by Stephen and the build test system. They were both introduced by my patches that you applied lately.

Thanks,
Daniel

Make of_mdiobus_link_phydev externally available.
This fixes CONFIG_OF_MDIO=m.
