timekeeping: Add missing parameter docs for pvclock_gtod_[un]register_notifier()

The kernel-doc parser complains about:
 kernel/time/timekeeping.c:651: warning: Function parameter or member
 'nb' not described in 'pvclock_gtod_register_notifier'
 kernel/time/timekeeping.c:670: warning: Function parameter or member
 'nb' not described in 'pvclock_gtod_unregister_notifier'

Add the missing parameter explanations.
