Xiong Zhang 4a356f670a pcie: Add PME support 
When virtual pcie root port RTD3 is enabled, it will enter into suspend if child device
isn't exist. Pcie hp driver disable hotplug interrupt once it enters into suspend state,
so hotplug interrupt couldn't be injected into guest if pcie RP is in suspend state. In
such case a PME will be injected into CrOS to wakeup itself first, another hotplug event
will be injected after this PME.

BUG=b:185084350
TEST=Hotplug a vfio-pci device into CrOS with virtual RP RTD3 enabled

crosvm - The Chrome OS Virtual Machine Monitor

crosvm is a virtual machine monitor (VMM) based on Linux’s KVM hypervisor, with a focus on simplicity, security, and speed. crosvm is intended to run Linux guests, originally as a security boundary for running native applications on the Chrome OS platform. Compared to QEMU, crosvm doesn’t emulate architectures or real hardware, instead concentrating on paravirtualized devices, such as the virtio standard.

crosvm is currently used to run Linux/Android guests on Chrome OS devices.
