[Sound-open-firmware] [RFC PATCH v2 5/5] APL/CNL: Initialize DMA trace data structure and definition on APL/CNL.

[yan.wang at linux.intel.com]

From: Yan Wang <yan.wang at linux.intel.com>

Add dma_trace_init_complete() calling on APL/CNL platform.
And use DMA_HOST_IN_DMAC as PLATFORM_TRACE_DMAC for DMA trace copying.
