virtio: list legacy-capable devices
Several types of virtio devices had already been around before the virtio standard was specified. These devices support virtio in legacy (and transitional) mode. Devices that have been added in the virtio standard are considered non-transitional (i.e. with no support for legacy virtio). Provide a helper function so virtio transports can figure that out easily.
