[PATCH 1/1] dmaengine: dmatest: use dmaengine_submit() and dmaengine_desc_set_callback()

[Frank.Li@oss.nxp.com]

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

Direct assignment to tx->callback and tx->callback_param bypasses the
dmaengine descriptor API. Replace them with dmaengine_desc_set_callback()
and replace the tx->tx_submit() call with dmaengine_submit(), which are
the proper interfaces for dmaengine clients.

Prepare to make struct dma_async_tx_descriptor private.
