O.K. So that makes it similar to the mv88e6xxx. With that driver, i
kept interrupt setup and mdio setup separate. I add the interrupt
controller first, and then do mdio setup, calling a helper to map the
PHY interrupts and assign them to bus->irq[].

That gives you a cleaner structure when you start using the other
interrupts.
