s390x: split flic into kvm and non-kvm parts

Browse source 
Introduce a common parent class for both cases, where kvm and non-kvm
can hook up callbacks. This will be used by follow-on patches for
adapter registration and mapping.

We now always have a flic, regardless of whether we use kvm; the
non-kvm implementation just doesn't do anything.
