From: David Brownell <david-b@pacbell.net>
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.
