I remember this corner case now [1] and it was easy to miss this. So
you want the OPP core to still parse the DT to read opp-hz, but don't
want dev_pm_opp_set_opp() to update the clock rate for it.

What was the reason for this again ?

I have a couple of solutions in mind, but one may be other than second
and so want to know the real issue at hand first.
