[PATCH 8/8] of: Add debug output for OF_RECONFIG notifiers

[Grant Likely <grant.likely-QSEj5FYQhm4dnm+yROfE0A@public.gmane.org>]

Add some additional debug output to cover OF_RECONFIG notifier activity.
At the same time, refactor the changeset debug output to use the same
strings as the notifier debug output.
