[Sound-open-firmware] [RFC PATCH v2 01/29] Define IPC message type and data structure for trace level.

[yan.wang at linux.intel.com]

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

For supporting trace level control based different modules, need
define one new IPC message type and data structure to transfer trace
levels of different global DMA trace type or component id from
kernel driver to SOF side.
