Currently there are no devices that can connect to pcie-root. For a
usable q35 system, we still need to add a "dmi-to-pci-bridge" pci
controller, which can connect to pcie-root, and provides pci slots.
Presumably you have another patch which auto-adds a 'dmi-to-pci-bridge'
device when we see a q35 machine, so that auto-PCI address assignment
still works ? If we relied on the user to add that device, then legacy
apps will not work against a QEMU which defaults to q35, since they'll
be adding PCI devices but not know that they need to add this bridge.
