dmaengine: imx-dma: configure the generic DMA type to make it work
[ Upstream commit7199ddede9
] Commitdea7a9fbb0
("dmaengine: imx-dma: remove dma_slave_config direction usage") changes the method from a "configuration when called" to an "configuration when used". Due to this, only the cyclic DMA type gets configured correctly, while the generic DMA type is left non-configured. Without this additional call, the struct imxdma_channel::word_size member is stuck at DMA_SLAVE_BUSWIDTH_UNDEFINED and imxdma_prep_slave_sg() always returns NULL.
