Subject: [PATCH v6 09/10] 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 the motherboard launched by Radxa. See below for
detail:
https://docs.radxa.com/en/orion/o6/getting-started/introduction
In this commit, it adds sky1 base, mailbox, clock (scmi firmware baseed)
and uart, and the kernel could boot up to console.

Changes for v6:
- Add mailbox, scmi and uart support
Changes for v5:
- Delete pmu-spe node which need to refine, and add it in future
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"
