powerpc+of: Rename and fix OF reconfig notifier error inject module

This module used to inject errors in the pSeries specific dynamic
reconfiguration notifiers. Those are gone however, replaced by
generic notifiers for changes to the device-tree. So let's update
the module to deal with these instead and rename it along the way.

 	  This option provides the ability to inject artifical errors to
-	  pSeries reconfig notifier chain callbacks.  It is controlled
+	  OF reconfig notifier chain callbacks.  It is controlled
 	  through debugfs interface under
-	  /sys/kernel/debug/notifier-error-inject/pSeries-reconfig/
+	  /sys/kernel/debug/notifier-error-inject/OF-reconfig/
 
 	  If the notifier call chain should be failed with some events
 	  notified, write the error code to "actions/<notifier event>/error".
