Heinz Graalfs 477a72a1ef s390x/event-facility: code restructure 
Code restructure in order to simplify class hierarchy
  - remove S390SCLPDevice abstract base class
    and move function pointers into new SCLPEventFacilityClass
  - implement SCLPEventFacility as SysBusDevice
  - use define constants for instance creation strings

The following ascii-art shows the class structure wrt the SCLP EventFacility
before (CURRENT) and after the restructure (NEW):

   |   SCLPEventFacility     |  - to be replaced by new SCLPEventFacility,
