Since e7f4dc3536a ("mdio: Move allocation of interrupts into core"),
platforms which call fixed_phy_add() before fixed_mdio_bus_init() is
called (for example, because the platform code and the fixed_phy driver
use the same initcall level) crash in fixed_phy_add() since the
->mii_bus is not allocated.

Also since e7f4dc3536a, these interrupts are initalized to polling by
default.  All callers of both fixed_phy_register() and fixed_phy_add()
pass PHY_POLL for the irq argument, so we can fix these crashes by
simply removing the irq parameter, since the default is correct for all
users.

Applied.
