Subject: [PATCH 04/10] arm64: dts: qcom: sm8450: Update cpuidle states parameters

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.

Cc: devicetree@...r.kernel.org
