[PATCH V4 4/9] virtio: rename dma_dev to map_token

[Jason Wang <jasowang@redhat.com>]

Following patch will introduce the mapping operations for virtio
device. So this patch rename dma_dev to map_token to match the
rework. The idea is the allow the transport layer to pass device
specific mapping token which will be used as a parameter for the
virtio mapping operations.
