The Smartbond SPI driver enables DMA acceleration by default. However no DMA configuration is provided in the SPI node, resulting in run time errors when the SPI interface is used. Instead, the application should explicitly enable DMA acceleration and select the DMA channels and priorities. Signed-off-by: Ian Morris <ian.d.morris@outlook.com>
