I think from an interface point of view it's something like
UNIVERSAL_DEV_PM_OPS() and friends, probably with some additional ops
that can do the glue bits like enabling wakeup and quiescing activity.
I'd need to think harder about what exactly that'd look like - for my
cases the fundamental thing I want to say is that there's one suspend
routine and one resume routine and I'd like some framework code to work
out when they're called.
