[PATCH v5 RESEND 5/5] riscv64: dts: sophgo: add initial Milk-V Duo S board support

[Joshua Milas]

Hi Shuwei,

Thanks for testing! I am seeing the same wifi issue on my end and have been
looking into it so it may not be a config issue.

I was able to get the chip enumerated by adding some properties to the sdhci1
node and adding some quirks to the kernel source on reset. I was also not able
to get the chip powered without manually toggling PORTA pin 15 in code. Then I
tried using the aic8800 1.0.9 dkms module however it needs some changes because
it is not updated for Linux 7.1. I did find some Milk-V Duo S AIC8800 drivers
and will give it a shot soon.

Thanks again,
- Joshua Milas
