Anton Vorontsov 5c15a6869a 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

  kernel BUG at arch/powerpc/include/asm/dma-mapping.h:237!

This patch fixes the issue by using card's device instead.
