clocksource: Remove unused WATCHDOG_INTERVAL_NS macro

WATCHDOG_INTERVAL_NS has been unused since it was introduced by commit
763aacf86f ("clocksource: Rewrite watchdog code completely"); the
watchdog timer rearming uses WATCHDOG_INTERVAL (in jiffies) directly and
the nanosecond variant has never had a user.

Remove the dead macro.  No functional change.
