The following build failure occurs when CONFIG_PERF_EVENTS is not set
as generic pmu functions are not visible in that scenario.
arch/powerpc/platforms/pseries/papr_scm.c:372:35: error: ‘struct perf_event’ has no member named ‘attr’

Fix the build issue by adding check for CONFIG_PERF_EVENTS config option
and also add stub function for papr_scm_pmu_register to handle
the CONFIG_PERF_EVENTS=n case. Also move the position of macro
"to_nvdimm_pmu" inorder to merge it in CONFIG_PERF_EVENTS=y block.
