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

[Joshua Milas]

Hello Michael,

Thanks for your explanation, I didn't know it might cause an error.
My plan is it enable i2c4, uart0, and spi3 since those are the
default on the pinctrl mux. I have tested uart0 and i2c4, but I am
getting an error with SPI

[    2.423553] dw_spi_mmio 41b0000.spi: DMA init failed

Not sure what is going on. I have the DMA controller enabled and it
seems to be initalizing correctly.

[    0.732791] dw_axi_dmac_platform 4330000.dma-controller: DesignWare AXI DMA Controller, 8 channels

Let me submit v3 so I can get some eyes on it.

Thanks,
- Joshua Milas
