This patch implements the static part of the s390 cpu class definitions.
It defines s390 cpu models by means of virtual cpu ids (enum) which contain
information on the cpu generation, the machine class, the GA number and
the machine type. The cpu id is used to instantiate a cpu class per cpu
model.
In addition the patch introduces the QMP enumeration AccelId. It is used
to index certain cpu model poperties per accelerator.
Furthermore it extends the existing S390CPUClass by model related properties.
