tests/device-plug: Add a simple PCI unplug request test
The issue with testing asynchronous unplug requests it that they usually
require a running guest to handle the request. However, to test if
unplug of PCI devices works, we can apply a nice little trick on some
architectures:
On system reset, x86 ACPI, s390x and spapr will perform the unplug,
resulting in the device of interest to get deleted and a DEVICE_DELETED
event getting sent.
On s390x, we still get a warning
qemu-system-s390x: -device virtio-mouse-pci,id=dev0:
warning: Plugging a PCI/zPCI device without the 'zpci' CPU feature
enabled; the guest will not be able to see/use this device
This will be fixed soon, when we enable the zpci CPU feature always
(Conny already has a patch for this queued).
