This patch itself does not implement deferral for spi-imx if dmaengine
not ready. The patch targets 2 things: give a bit more detailed error
information of SPI dma slave channel initialization error and provide a
basis for the next patch ([PATCH v3 7/7] spi: imx: defer spi
initialization, if DMA engine is pending).
