Disabled by default, enable using '-machine q35,x-svsm-virtio-mmio=on'.
When enabled it is possible to plug up to 4 virtio devices into the
slots virtio-mmio using '-device virtio-${kind}-device'.
The devices can be found at base address 0xfef00000, each slot on a
separate page. No IRQ is wired up, the svsm has to drive the devices
in polling mode.
