 timecounter: Merge FreeBSD change r286429

 Only process the PPS event types currently enabled in pps_params.mode.

 This makes the PPS API behave correctly, but isn't ideal -- we still end
 up capturing PPS data for non-enabled edges, we just don't process the
 data into an event that becomes visible outside of kern_tc.  That's
 because
 the event type isn't passed to pps_capture(), so it can't do the
 filtering.
 Any solution for capture filtering is going to require touching every
 driver.

 Update #3175.
