Update the reachability register of a refclock source by 1 if a valid measurement is received by the drivers between source polls, and not only when it is accumulated to sourcestats, similarly to how reachability works with NTP sources. This avoids drops in the reported reachability when a PHC refclock is dropping samples due to significant changes in the measured delay (e.g. due to high PCIe load), or a PPS refclock dropping samples due to failed lock.
