This has a variety of updates to the shared suspend/resume code for
PCI based USB host controllers.
- Cope with pm_message_t replacing the target system state.
This is actually a loss of functionality; PCI D1 and D2
states will no longer be used, and it's no longer knowable
that D3cold is on the way so power will be lost.
- Most importantly, some of the resume paths are reworked and
cleaned up. They're now an exact mirror of suspend paths,
and more care is taken to ensure the hardware is reactivated
before the hardware re-enables interrupts.
Plus comment and diagnostic cleanups; there are some nasty cases here
especially combined with swsusp, now they're somewhat commented.
