PCI: Add support for polling PME state on suspended legacy PCI devices

Browse source

Not all hardware vendors hook up the PME line for legacy PCI devices,
meaning that wakeup events get lost. The only way around this is to poll
the devices to see if their state has changed, so add support for doing
that on legacy PCI devices that aren't part of the core chipset.
