Subject: [PATCH v4 5/6] arm64: dts: cix: add initial CIX P1(SKY1) dts support
CIX SKY1 SoC is high performance Armv9 SoC designed by Cixtech,
and Orion O6 is open source motherboard launched by Radxa.
See below for detail:
https://docs.radxa.com/en/orion/o6/getting-started/introduction
In this commit, it only adds limited components for running initramfs
at Orion O6.

Changes for v4:
- Add ppi-partition entry for gic-v3 node, and let pmu-a520 and pmu-a720's interrupt entry
get its handle
- Remove gic-v3's #redistributor-regions and redistributor-stride properties
- Change gic-v3's #interrupt-cells as 4, and change all interrupt specifiers accordingly
- Remove "arm,no-tick-in-suspend" for timer due to global counter is at always-on power domain
- Remove timer's clock frequency due to firmware has already set it
- Add Krzysztof Kozlowski's reviewed-by
Changes for v3:
- Fix two dts coding sytle issues
Changes for v2:
- Corrects the SoF tag's name
- Fix several coding sytle issues
- move linux,cma node to dts file
- delete memory node, memory size is passed by firmware
- delete uart2 node which will be added in future patches
- Improve for pmu and cpu node to stands for more specific cpu model
- Improve the timer node and add hypervisor virtual timer irq
- Pass "make O=$OUTKNL CHECK_DTBS=y W=1 cix/sky1-orion-o6.dtb"
