  s390x/virtio-ccw: Adapter interrupt support.

Handle the new CCW_CMD_SET_IND_ADAPTER command enabling adapter interrupts
on guest request. When active, host->guest notifications will be handled
via global_indicator -> queue indicators instead of queue indicators +
subchannel I/O interrupt. Indicators for virtqueues may be present at an
offset.

One patch introducing support for adapter interrupts in virtio-ccw.

This improves performance for those guests that issue the new
CCW_CMD_SET_IND_ADAPTER channel command.
