In general, parallel suspend/resume isn't easy to do correctly. There are lots of constraints on the order in which devices can be suspended, many of them not explicitly stated anywhere. I don't think it is feasible to encapsulate the constraint information in the PM core; if anything, it should be left up to the individual subsystems to suspend or resume their devices in parallel.
