[PATCH 1/4] ASoC: apple: mca: Use dmaengine_get_dma_device() instead of chan->device->dev

[Frank . Li]

From: Frank Li <Frank.Li@xxxxxxx>

Replace open-coded chan->device->dev with the accessor
dmaengine_get_dma_device() to avoid direct access to DMA engine
internals.

Prepare to make struct dma_device private.
