[PATCH v2] arm64: dts: cix: Add SCMI performance domains for CPUFreq on Sky1

[Devin Li]

Add SCMI Protocol 13 (Performance) node under ap_to_pm_scmi with
domains.

Define SKY1_PERF_* macros in sky1-power.h for all performance domain
IDs (CPU L/B0/B1/M0/M1, GPU, DSU, NPU, VPU, CI700, NI700), and
wire each CPU node to its corresponding performance domain using
power-domains and power-domain-names properties.

    Change for v2:
    - Use real name format "Devin Li"
