PM: PCI and IDE handle PM_EVENT_PRETHAW

Browse source 
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.
