Benjamin Herrenschmidt d526e85f60 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.
