pcm suspend/resume cleanup #570
Description
we should do it like this:
suspend:
- send stream trigger stop IPC(to FW) in sof_pcm_trigger() when TRIGGER_SUSPEND arrive, and mark spcm->restore_stream[] to be true;
- (after multiple ssp and icelake support #1 done for all PCMs) send suspend IPC(context_save) to FW, and suspend ADSP.
resume:
- send resume IPC(context_restore) to FW (after FW rebooted).
- send stream trigger start IPC(to FW) in sof_pcm_trigger() when TRIGGER_RESUME arrive(if spcm->restore_stream[] is true), and mark spcm->restore_stream[] back to be false;
But now this is messed, we need cleanup it.

remember the 3 steps:
Also why is this an "enhancement"?
