From: Yan Wang yan.wang@linux.intel.com
1. Add SOF_IPC_GLB_TRACE_MSG class of IPC communication. 2. Add two IPC commands for DMA tracing. a) SOF_IPC_TRACE_DMA_INIT is used to initilize local buffer on DSP side. b) SOF_IPC_TRACE_DMA_PARAMS is used to receive host DMA buffer PHY. 3. Define DMA for Trace params IPC info structure.
