[3/4] hw/s390x/s390-virtio-ccw: Remove the deprecated 3.1 machine type

Commit Message

From: Thomas Huth <[e-mail]>

The s390-ccw-virtio-3.1 machine is older than 6 years, so according to
our machine support policy, it can be removed now. The corresponding
v3.1 CPU feature group can now be removed, too.
