Measure latency does by itself contribute to an increased latency, thus we should avoid it when it isn't needed. Genpd measures latencies in the system PM phase for the ->start|stop() callbacks and is thus affecting the system PM suspend/resume time. Moreover these latencies are validated only at runtime PM suspend/resume. To this reasoning, let's decide to leave these measurements out of the system PM phase. There should be plenty of occasions during runtime PM to perform these measurements anyway.
