From: Maulik Shah <quic_mkshah@quicinc.com>

[ Upstream commit 6574702b0d394d2acc9ff808c4a79df8b9999173 ]

This change updates/corrects below cpuidle parameters

1. entry-latency, exit-latency and residency for various idle states.
2. arm,psci-suspend-param which is same for CLUSTER_SLEEP_0/1 states.
3. Add CLUSTER_SLEEP_1 in CLUSTER_PD.
