PCI PM: Power-manage devices without drivers during suspend-resume

Browse source

PCI devices without drivers can be put into low power states during
suspend with the help of pci_prepare_to_sleep() and prevented from
generating wake-up events during resume with the help of
pci_enable_wake().  However, it's better not to put bridges into
low power states during suspend, because that might result in entire
bus segments being powered off.
