Yes, this only handles acpi hotplug of devices behind the root. I'm
trying to reach minimal set of q35 patches that we can build upon. I
think that this patch gives us at least the same functionality as piix
does. (Plus there is pcie hotplug).

As you know, I have a proof of concept patch series providing a second
level of hotplug behind bridges. Unfortunately, it was based on the
static acpi tables, before Paolo made the hotplug table generation
dynamic. So it needs quite a bit of re-work. But I know that it should
work :)
