Hi!

Add a functional test, aarch64_hotplug_pci, to exercise PCI hotplug and
hot-unplug on arm64. Currently, the aarch64 'virt' machine uses the PCIe
native controller and does not support ACPI-based hotplugging. However,
since support is planned, this test sets 'acpi=force' and specifies an
EDK2 firmware image in advance. This is harmless and prepares for future
ACPI support.

Please use self.set_machine('virt') instead so that the test gets correctly
skipped in case the machine has not been compiled into the binary.
Thanks,
