Heinz Graalfs ab9074b559 s390: sclp signal quiesce support
This implements the sclp signal quiesce event via the SCLP Event
Facility.
This allows to gracefully shutdown a guest by using system_powerdown
notifiers. It creates a service interrupt that will trigger a
Read Event Data command from the guest. This code will then add an
event that is interpreted by linux guests as ctrl-alt-del.
