This patch defines S390 cpu facilities and their presence at the
different cpu model levels. Beside defining a base which facilities
have to be requested per cpu model, these sets are associated to the
defined cpu classes and used to calculate the list of supported
cpu models in context of the current hosting machine model.
The also defined qemu side facility mask allows to implement and enable
facilities in QEMU land.
