To support driver model and device tree, use the SPI-flash-based AT45xxx DataFlash driver, DataFlash is a kind of SPI flash. Instead of ATMEL_DATAFLASH_SPI DataFlash older driver that will be removed in the future. Signed-off-by: Wenyou Yang <wenyou.yang@microchip.com> Reviewed-by: Simon Glass <sjg@chromium.org>
