Ah, very nice! This way it will actually work to replace a number
of older drivers that require a specific clock name.

I still think we should change the phy subsystem to allow the
same, that would make it more consistent here, and avoid the
need for coming up with a number of bogus phy names for random
drivers that can only ever have one phy.
