Dapeng Mi aa4384bc8f perf/x86/intel: Enable auto counter reload for DMR
Panther cove µarch starts to support auto counter reload (ACR), but the
static_call intel_pmu_enable_acr_event() is not updated for the Panther
Cove µarch used by DMR. It leads to the auto counter reload is not
really enabled on DMR.

Update static_call intel_pmu_enable_acr_event() in intel_pmu_init_pnc().
