[PATCH v15 clocksource 6/6] clocksource: Print deviation in nanoseconds for unstable case

[Paul E. McKenney]

From: Feng Tang <feng.tang@xxxxxxxxx>

Currently when an unstable clocksource is detected, the raw counters
of that clocksource and watchdog will be printed, which can only be
understood after some math calculation.  So print the existing delta in
nanoseconds to make it easier for humans to check the results.
