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.

This adds a more generic infrastructure for handling Service-Call
requests on s390. Currently we only support a small subset of Read
SCP Info directly in target-s390x. This patch provides the base
infrastructure for supporting more commands and moves Read SCP
Info.
In the future we could add additional commands for hotplug, call
home and event handling.
