All users of the fixed_phy_add() pass -1 as GPIO number to the fixed phy driver, and all users of fixed_phy_register() pass -1 as GPIO number as well, except for the device tree MDIO bus. Any new users should create a proper device and pass the GPIO as a descriptor associated with the device so delete the GPIO argument from the calls and drop the code looking requesting a GPIO in fixed_phy_add(). In fixed phy_register(), investigate the "fixed-link" node and pick the GPIO descriptor from "link-gpios" if this property exists. Move the corresponding code out of of_mdio.c as the fixed phy code anyways requires OF to be in use.
