virtio/s390: DMA support for virtio-ccw
Currently virtio-ccw devices do not work if the device has VIRTIO_F_IOMMU_PLATFORM. In future we do want to support DMA API with virtio-ccw. Let us do the plumbing, so the feature VIRTIO_F_IOMMU_PLATFORM works with virtio-ccw. Let us also switch from legacy avail/used accessors to the DMA aware ones (even if it isn't strictly necessary), and remove the legacy accessors (we were the last users).
