There are two free-running counters for client IMC uncore. The customized event_init() function hard codes their index to 'UNCORE_PMC_IDX_FIXED' and 'UNCORE_PMC_IDX_FIXED + 1'. To support the index 'UNCORE_PMC_IDX_FIXED + 1', the generic uncore_perf_event_update is obscurely hacked. The code quality issue will bring problems when a new counter index is introduced into the generic code, for example, a new index for free-running counter. Introducing a customized event_read() function for client IMC uncore. The customized function is copied from previous generic uncore_pmu_event_read(). The index 'UNCORE_PMC_IDX_FIXED + 1' will be isolated for client IMC uncore only.
