s390: sclp event support

Several SCLP features are considered to be events. Those events don't provide SCLP commands on their own, instead they are all based on Read Event Data, Write Event Data, Write Event Mask and the service interrupt. Follow-on patches will provide SCLP's Signal Quiesce (via system_powerdown) and the ASCII console. Further down the road the sclp line mode console and configuration change events (e.g. cpu hotplug) can be implemented.
