powerpc/perf: Fix perf_get_data_addr() for power9 DD1
Power9 DD1 do not support PMU_HAS_SIER flag and sdsync in
perf_get_data_addr() defaults to MMCRA_SDSYNC which is wrong. Since
power9 MMCRA does not support SDSYNC bit, patch includes PPMU_NO_SIAR
flag to the check and set the sdsync with MMCRA_SAMPLE_ENABLE;
