[PATCH 1/1] ASoC: fsl_asrc_m2m: use dma_chan directly for dma_async_issue_pending()

[Frank.Li@oss.nxp.com]

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

Use pair->dma_chan[] directly instead of pair->desc[]->chan when calling
dma_async_issue_pending(), which is more straightforward and avoids
dereferencing the descriptor to get the channel.

Prepare to make struct dma_async_tx_descriptor private.
