[PATCH 3/5] cpuidle-pseries : Fixup exit latency for CEDE(0)

From: "Gautham R. Shenoy" We are currently assuming that CEDE(0) has exit latency 10us, since there is no way for us to query from the platform. However, if the wakeup latency of an Extended CEDE state is smaller than 10us, then we can be sure that the exit latency of CEDE(0) cannot be more
