[virtio] Support VIRTIO_NET_F_IOMMU_PLATFORM
Since we don't enable IOMMU at all, we can then simply enable the IOMMU support by claiming the support of VIRITO_F_IOMMU_PLATFORM. This fixes booting failure when iommu_platform is set from qemu cli. Signed-off-by: Jason Wang <jasowang@redhat.com> Signed-off-by: Michael Brown <mcb30@ipxe.org>
