Subject: [PATCH] powernv/cpuidle: Fix idle states all being marked invalid

From: Nicholas Piggin <[email-masked]>
Date: Fri, 3 Aug 2018 01:39:51 +1000

Commit 9c7b185ab2 ("powernv/cpuidle: Parse dt idle properties into
global structure") parses dt idle states into structs, but never
marks them valid. This results in all idle states being lost.
