While I think all the clocks should use a similar binding to the clkctrl
binding, I don't know if it makes sense to start changing things around
at such a large scale.

Certainly if somebody does the patches and they can be tested to not cause
regressions, sure why not :)

Best to fix the issues first, then make any clean-up patches a separate
series.
