Intel® Arria® 10 SoC. Cadence Quad SPI Flash is not generic SPI controller, but SPI flash controller, so don't use spibus here, instead provide quad spi flash interface. Since it is not on spibus, then mx25l flash device driver is not usable here, so provide new n25q flash device driver with quad spi flash interface.
