No, if I were going to do anything here it'd be converting everything
over to the common clock API so we didn't have to deal with this sort
of issue, it really makes the clock API unusable for generic code.

Yes, if it's a reusable IP then it's going to have a fixed set of clocks
which go into it regardless of which platform it's hooked up to.  clkdev
provides an abstraction which can map these onto the platform, even if
you don't use the generic clk API clkdev is still very useful and will
help with a lot of these issues.
