[PATCH 5/5] cpuidle-pseries: Block Extended CEDE(1) which adds no additional value.

From: "Gautham R. Shenoy" The Extended CEDE state with latency-hint = 1 is only different from normal CEDE (with latency-hint = 0) in that a CPU in Extended CEDE(1) does not wakeup on timer events. Both CEDE and Extended CEDE(1) map to the same hardware idle state. Since we already get SMT foldin
