Since we have one for virtio, it seems neater to use that rather than LNRO. For the device ID, use 103F which is a legacy ID that isn't used in virtio PCI spec - seems to make sense since virtio-mmio is a legacy device but we don't know the correct device type. Guests should probably match everything in the range 1000-103F (just like legacy pci drivers do) which will allow us to pass in the actual ID in the future if we want to. Signed-off-by: Michael S.
