Andreas Färber c7396bbb25 target-s390x: Mark as unmigratable
CPU_SAVE_VERSION was undefined, so "cpu_common" VMState and
cpu_{save,load}() were not registered. They were no-ops.
Therefore there is no backwards compatibility to keep, so we can mark
S390CPU as unmigratable at device level.

Christian Borntraeger 000a1a3800 s390: provide interface for service interrupt/introduce interrupt.c
This patch creates interrupt.c. The first user is a callback for hw/*
code to trigger an service interrupt for a given sccb value. Several
interrupt types for s390 are floating (can be delivered to all CPUs).
so this code does not belong to a specific CPU.
Other interrupts (like the virtio one) are also floating and can be
moved here later on.
