dm: sf: Make SST flash write op work again
With SPI flash moving to driver model, commit fbb0991 "dm: Convert spi_flash_probe() and 'sf probe' to use driver model" ignored the SST flash-specific write op (byte program & word program), which actually broke the SST flash from wroking. This commit makes SST flash work again under driver model, by adding SST flash-specific handling in the spi_flash_std_write().
