PM: PCI and IDE handle PM_EVENT_PRETHAW
Convert some framework code to handle the new PRETHAW message.
- IDE just treats it like a FREEZE.
- The pci_choose_state() thingie still doesn't use PCI_D0 when it gets a
FREEZE (and now PRETHAW) event, which seems rather buglike but wasn't
something to change with this patch.
