The boot-bypass bit isn't a hard dependency for this series, but it will
be needed for full support eventually. It will be delayed by spec and
Linux header changes

In the meantime we can work around the problem by having the boot disks
bypass the IOMMU (virtio without iommu-platform, or iommu-bypass bus).

Thanks,
Jean
