[PATCH 2/4] hw/s390x/sclp: Have sclp_service_call[_protected]() take S390CPU*

["Philippe Mathieu-Daudé" <philmd@linaro.org>]

"hw/s390x/sclp.h" is a header used by target-agnostic objects
(such hw/char/sclpconsole[-lm].c), thus can not use target-specific
types, such CPUS390XState.

Have sclp_service_call[_protected]() take a S390CPU pointer, which
is target-agnostic.
