KVM: s390: enable MSA9 keywrapping functions depending on cpu model

Browse source

Instead of adding a new machine option to disable/enable the keywrapping
options of pckmo (like for AES and DEA) we can now use the CPU model to
decide. As ECC is also wrapped with the AES key we need that to be
enabled.
