hw/acpi/ged: Prepare the device to react to PCI hotplug events
QEMU will notify the OS about PCI hotplug/hotunplug events through
GED interrupts. Let the GED device handle a new PCI hotplug event.
On its occurrence it calls the \\_SB.PCI0.PCNT method with the BLCK
mutex held.
The GED device uses a dedicated MMIO region that will be mapped
by the machine code.
At this point the GED still does not support PCI device hotplug in
its TYPE_HOTPLUG_HANDLER implementation. This will come in a
subsequent patch.
