hw/virtio-pci: fix virtio behaviour
Enable transitional virtio devices by default.
Enable virtio-1.0 for devices plugged into
PCIe ports (Root ports or Downstream ports).
Using the virtio-1 mode will remove the limitation
of the number of devices that can be attached to a machine
by removing the need for the IO BAR.
