KVM: S390: add new group for flic
In some cases, userspace needs to get or set all ais states for example migration. So we introduce a new group KVM_DEV_FLIC_AISM_ALL to provide interfaces to get or set the adapter-interruption-suppression mode for all ISCs. The corresponding documentation is updated.
