KVM: s390: Support for I/O interrupts.
Add support for handling I/O interrupts (standard, subchannel-related
ones and rudimentary adapter interrupts).
The subchannel-identifying parameters are encoded into the interrupt
type.
I/O interrupts are floating, so they can't be injected on a specific
vcpu.
