I'm not entirely convinced we can keep them separated, the moment we
have multiple CPUs sharing a P or C state we need somewhere to manage
the shared state and the domain tree seems like the most natural place
for this.

Now it might well be both P and C states operate at 'natural' domains
which we already have so it might be 'easy'.
