[PATCH v5 3/3] arm64: dts: rockchip: Add support for CM5 IO carrier

[Dmitriy Filchenko]

Should `vdd_cpu_lit_s0` and some others be in the SoM device tree instead of the IO board? I see it on page 18 of the schematic https://dl.radxa.com/cm5/v2210/radxa_cm5_v2210_schematic.pdf

Additionally, I am getting the following during boot:
```
[   38.190604] rockchip-pm-domain fd8d8000.power-management:power-controller: Failed to create device link (0x180) with supplier spi2.0 for /power-management at fd8d8000/power-controller/power-domain at 12
```

The device is an RK3588s CM5 on the IO board powered through the barrel jack.
