Applied. The intention for trace is the pipeline/component copy() and IRQ trace
messages should be verbose due their high frequency.

In 1.2 I'd like to see a debugFS file that can enable/disable trace and verbose
trace per subsystem/component at runtime.

e.g.

echo off > /sys/kernel/debug/sof/trace_level
echo on > /sys/kernel/debug/sof/trace_level
echo src > /sys/kernel/debug/sof/trace_level
echo pipeline > /sys/kernel/debug/sof/trace_level
echo scheduler > /sys/kernel/debug/sof/trace_level
