Aside from the whole PM_OPP question; you should assert that assumption.
Put an explicit check for the uarch in and FAIL the init if that isn't

I don't think it makes _ANY_ kind of sense to share a frequency domain
across uarchs and we should be very clear we're not going to support
anything like that.

I know DynamiQ strictly speaking allows that, but since it's insane, we
should consider that a bug in DynamiQ.
