[PATCH 1/1] ASoC/sound: use dmaengine_desc_set_callback()

[Frank.Li at oss.nxp.com]

From: Frank Li <Frank.Li at nxp.com>

Replace open-coded assignments to callback and callback_param fields
of struct dma_async_tx_descriptor with calls to the
dmaengine_desc_set_callback() helper across sound drivers.

No functional change intended. Prepare to make struct
dma_async_tx_descriptor private to the DMA engine.
