Usually, it is not fully customized. Most of the counter operation functions can still use the generic code. For example, it only needs to customize init() function for client IMC uncore. Other counter operation functions, add()/del()/start()/stop()/read(), can still use the generic code. Expose the pmu counter operation functions uncore_pmu_event_add/del/start/stop.
