[PATCH] cpuidle/powernv: Re-enable fastsleep at boot time

From: Preeti U Murthy
Date: Tue Nov 18 2014 - 01:56:30 EST

Commit dcb18694 "Fix ipi on palmeto" disabled fastsleep at boot time.
Revert this commit since we no longer need this fix. However we can
continue to use powersave_nap parameter to control entry into deep
idle states beyond snooze.
