We want the trig_sts bits to be cleared in all cases where we consider the jack detection interrupt to have been handled. Specifically, if a duplicate detection event was suppressed these bits were not cleared causing the CODEC to not enter a low power state. This patch clears the bits on the duplicate detection code path.
