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

[Joshua Milas]

Hi Shuwei,

I was able to get the wifi chip working. It requires the proper DT and an
updated aic8800-milkv-duo-s driver [1] that has been updated to Linux 7.1.
The next patch will cover the DT part.
