If PERF_EVENTS is not set, bulding fails:

drivers/nvdimm/nd_perf.o: In function `nvdimm_pmu_cpu_offline':
nd_perf.c:(.text+0x12c): undefined reference to `perf_pmu_migrate_context'
drivers/nvdimm/nd_perf.o: In function `register_nvdimm_pmu':
nd_perf.c:(.text+0x3c4): undefined reference to `perf_pmu_register'
drivers/nvdimm/nd_perf.o: In function `unregister_nvdimm_pmu':
nd_perf.c:(.text+0x4c0): undefined reference to `perf_pmu_unregister'

Make LIBNVDIMM depends on PERF_EVENTS to fix this.
