This is a "this device requires OPP n" property. Couldn't we want this
for cases other than a powerdomain OPP? What if a device has
requirements 2 different OPPs?

Hmm, I agree. We can/should make it more generic.

On the flipside, I don't think we want devices picking things like CPU
OPPs and putting policy here. But I'd rather things be extendable than
reviewing yet another OPP property next month.

Sure, I would rename this property and make necessary changes to it.
