The PCI power management specification requires that the OS clear any pending PME# interrupt and generation of PME# interrupts during "initial operating system load". Note that clearing a pending PME# interrupt requires writing a 1 to the Read/Write-Clear PME bit in the power management status register. To handle the boot time case, clear PME# state in pci_read_cap() when scanning new PCI devices. This should also cover hotplug devices. In addition, clear this state on every PCI device after resume from sleep in pci_resume_child before invoking the driver's DEVICE_RESUME method.
