ASoC: SOF: extend the interface to stop DMA trace

Change the interface to stop the DMA trace for suspend. Replace the
snd_sof_init_trace_ipc() and snd_sof_release_trace() calls with more
explicit interface for PM (the sole user for this interface).

The new snd_sof_trace_suspend() call takes the target PM state as argument,
allowing the trace implementation to decide how to handle the transition.
Use this information to release DMA resources only if DSP is suspended and
will not remain in D0.
