I don't understand that; drivers should not care about the names of
clocks; the names will be entirely irrelevant once we get clocks from DT.

I'd prefer to defer that until after we get clocks from DT. Otherwise,
we're just adding more churn to the old clock driver first. It'd be
better to just switch to the new clock driver, put all the clocks in DT,
and then build on that.
