Most LicheePi Nano boards come with soldered SPI flash, so enable SPI0 in the .dts and describe the flash chip. There is evidence of different flash chips used, also of boards with no flash chip soldered, but the Winbond 16MiB model is the most common, so use that for the compatible string. The actual flash chip model will be auto-detected at runtime anyway.
