[Sound-open-firmware] [RFC PATCH v2 03/29] Add trace level variable and set function for SOF modules.

[yan.wang at linux.intel.com]

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

SOF modules include comp_dev, comp_buffer and pipeline.
For trace level control based on modules, need add one variable
for every module type and set function.
