ASoC: fsl_asrc_dma: allocate memory from dma device

Browse source

The dma-coherent property is used to indicate a device is capable of
coherent DMA operations. On i.MX952, one of EDMA devices support such
feature, in order to support the EDMA device, the memory needs to be
allocated from the DMA device.

Make this driver to support both non dma-coherent and dma-coherent dma
engine.

Remove dma coerce_mask_and coherent() because DMA provider already set it
according to its capability.
