Niklas Cassel 6846d65610 riscv: dts: canaan: Fix SPI3 bus width ... According to the K210 Standalone SDK Programming guide: https://canaan-creative.com/wp-content/uploads/2020/03/kendryte_standalone_programming_guide_20190311144158_en.pdf Section 15.4.3.3: SPI0 and SPI1 supports: standard, dual, quad and octal transfers. SPI3 supports: standard, dual and quad transfers (octal is not supported). In order to support quad transfers (Quad SPI), SPI3 must have four IO wires connected to the SPI flash. Update the device tree to specify the correct bus width. Tested on maix bit, maix dock and maixduino, which all have the same SPI flash (gd25lq128d) connected to SPI3. maix go is untested, but it would not make sense for this k210 board to be designed differently.
