powerpc/pseries: Move smp_query_cpu_stopped() etc. out of plpar_wrappers.h
smp_query_cpu_stopped() and related #defines are currently in plpar_wrappers.h. The function actually does an RTAS call, not an hcall, and basically has nothing to do with plpar_wrappers.h Move it into pseries.h, where it can easily be used by the only two callers in pseries/smp.c and pseries/hotplug-cpu.c.
