No matter how we do this, we end up enforcing OPPs for genpds.

It means that we may be requesting the same performance-level that we
have already requested for the device. Of course genpd manages this,
but it just seems a bit in-efficient to mee. Or maybe this isn't a big
deal as consumer drivers should end up doing this anyway?
