  s390x/cpu: Cleanup init in preparation for hotplug

Ensure a valid cpu_model is set upfront by setting the
default value directly into the MachineState when none is
specified.  This is needed to ensure hotplugged CPUs share
the same cpu_model.

  s390x: Introduce machine definition macros

Most of the machine definition code looks the same between different
machine versions. The new DEFINE_CCW_MACHINE macro makes defining a
new machine easier by inserting standard machine version
definitions. This also makes it possible to propagate values between
machine versions.

The patch is inspired by code from hw/ppc/spapr.c

  s390x: Introduce S390MachineClass

As we now have the new machine definitions, that let us disable/enable
machine options more easily, we need a way to save them and make them
publicly available.

The new s390-virtio-ccw.h header exports the s390 ccw machine state
and class, so they can be easily used in other C files.
