    LinuxKPI: add skeleton pci_enable_wake()
    
    Given we do not yet support "wake" bits in device there is little need
    doing it in PCI if we cannot check if we are supposed to do the
    operation in first place.  Once we would implement this, we would need
    to also do the appropriate PCI (pme) checks before enabling (disabling)
    it.
