[PATCH 1/2] net: of_mdio: use int type for address variable

[Daniel Mack <zonque@gmail.com>]

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
