[PATCH 1/1] soc: tegra: use dmaengine_desc_set_callback()

[Frank . Li]

From: Frank Li <Frank.Li@xxxxxxx>

Replace open-coded assignments to callback and callback_param fields
of struct dma_async_tx_descriptor with a call to the
dmaengine_desc_set_callback() helper.

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