docs/s390: clarify even more that cpu-topology is KVM-only

At least for now cpu-topology is implemented only for KVM.

We already say this, but this tries to be more explicit,
and also show it in the examples.

This adds a new reference in the introduction that we can point to,
whenever we need to reference accelerators and how to select them.
