[PATCH for-6.2 v2] s390-sclp-events-bus: Use OBJECT_DECLARE_SIMPLE_TYPE

[Eduardo Habkost <ehabkost@redhat.com>]

We have a SCLPEventsBus struct type defined, but no QOM type
checkers are declared for the type.

Use OBJECT_DECLARE_SIMPLE_TYPE to declare the struct type and
have a SCLP_EVENT_BUS typecast wrapper defined.
