intel/perf: Do not add INTEL_PERF_QUERY_FIELD_TYPE_SRM_OA_PEC

Browse source 
MI_REPORT_PERF_COUNT reports all 64 PEC counters, so there is no
need to read individual registers.
Also the individual registers reads privileged and UMDs can't access
it, causing it to always read as always zero and overwritting valid
data read with MI_REPORT_PERF_COUNT.
