[S390] topology: get rid of ifdefs
Remove all ifdefs from topology code and also only compile it for the CONFIG_SCHED_BOOK case. The new code selects SCHED_MC if SCHED_BOOK is selected. SCHED_MC without SCHED_BOOK is not possible anymore. Furthermore various sysfs attributes are not available anymore for the !SCHED_BOOK case. In particular all attributes that correspond to CPU polarization. But since all real world kernels have SCHED_BOOK selected anyway this doesn't matter too much.
