When specific GPE event happens, some devices want to get notification. For example, virtual pcie root port wants to get notification when acpi hotplug GPE occurs. So virtual pcie root port implements this trait. When virtual pcie root port gets this hotplug GPE notification, it will inject a PME into CrOS, CrOS PME handler will wakeup virtual pcie root port and TBT DMA engine, and forbit them to enter into suspend again during hotplug process. Once hotplug process is finished, virtual pcie root port and TBT DMA engine could be allowed to suspend again.
