ASoC: fsl_dma: Pass the proper device for dma mapping routines
The driver should pass a device that specifies internal DMA ops, but
substream->pcm is just a logical device, and thus doesn't have arch-
specific dma callbacks, therefore following bug appears:
Freescale Synchronous Serial Interface (SSI) ASoC Driver
