To support DM QSPI driver - Add spi0 and spi1 alias for qspi1 and qspi2. - Modify n25q256a@0 and n25q256a@1 compatible string to "spi-flash" - Enable DM SPI/QSPI relavent configurations - Remove iomux settings of qspi2 in board codes which is not needed for DM driver. - Add sf default settings. So running "sf probe" can detect the flash
