[PATCH v2 3/3] arm64: dts: nuvoton: Add NuMaker board

[Jacky Huang]

> Nuvoton MA35D SoC is used on the NuMaker SoM, itself plugged onto a
> carrier board labelled NuMaker. Create a DTS including the SoM
> description. As a first external component, mention the SPI NAND
> connected to the Quad SPI controller.
