virtio-entropy: Maintain entropy device spec in separate directory

Move virtio entropy device specification to its own file similar to recent virtio devices. While at it, place device specification, its driver and device conformance into its own directory to have self contained device specification. Fixes: #153 Acked-by: Michael S. Tsirkin <mst@redhat.com> Signed-off-by: Parav Pandit <parav@nvidia.com> Signed-off-by: Cornelia Huck <cohuck@redhat.com>
