[PATCH 2/3] arm64: dts: sophgo: add initial Milk-V Duo S board support

[Joshua Milas]

Inochi,

Thanks for pointing me twards duo-pinmux. I was able to use it to get
the default config which is uart0, spi3, and i2c4. I can change the
dts to match, but...

> I suggest enabling devices that are accessed by default

Would we rather enable anything that can be accessed by the pinmux?

Thanks,
- Joshua Milas
