Commit f1d5516ab5 introduces a test in some iotests to check if
the machine is a s390-ccw-virtio and to select virtio-*-ccw rather
than virtio-*-pci.
We don't need that because QEMU already provides aliases to use the correct
virtio interface according to the machine type.
This patch removes all virtio-*-pci and virtio-*-ccw to use virtio-*
instead and remove get_virtio_scsi_device().
This also enables virtio-mmio devices (virtio-*-device)
