s390/perf_events: compile only for CONFIG_64BIT

The whole hardware support is only available in zArch mode.
Fixes also this compile warning:

arch/s390/kernel/perf_cpum_cf.c: In function ‘cpumf_pmu_init’:
arch/s390/kernel/perf_cpum_cf.c:670:2: warning: left shift count >= width of type [enabled by default]
