arm64: dts: cix: Add CPU idle states for Sky1
Add PSCI-based CPU idle state definitions for the Sky1 SoC,
enabling core and cluster level power management through
ARM PSCI firmware.
Three idle states are defined:
- CPU_SLEEP_0: Core idle state for A520 cores
(psci-suspend-param 0x0010000), entry-latency 34us,
exit-latency 100us
- CPU_SLEEP_1: Core idle state for A720 cores
(psci-suspend-param 0x10000), entry-latency 31us,
exit-latency 79us
- CLUSTER_SLEEP_0: Cluster idle state shared by all cores
(psci-suspend-param 0x1010000), entry-latency 41us,
exit-latency 104us
A520 cores (cpu0-3) reference CPU_SLEEP_0 and CLUSTER_SLEEP_0,
while A720 cores (cpu4-11) reference CPU_SLEEP_1 and
CLUSTER_SLEEP_0.
