Introduce functions pci_prepare_to_sleep() and pci_back_from_sleep(), to be used by the PCI drivers that want to place their devices into the lowest power state appropiate for them (PCI_D3hot, if the device is not supposed to wake up the system, or the deepest state from which the wake-up is possible, otherwise) while the system is being prepared to go into a sleeping state and to put them back into D0 during the subsequent transition to the working state.
