powerpc: pSeries reconfig notifier error injection module

This provides the ability to inject artifical errors to pSeries reconfig
notifier chain callbacks.  It is controlled through debugfs interface
under /sys/kernel/debug/notifier-error-inject/pSeries-reconfig

If the notifier call chain should be failed with some events
notified, write the error code to "actions/<notifier event>/error".
