Issue seems to be connected with SGPC - Shared Graphics Power Component. That
is, during power state change on gfx side, codec -or clock (not entirely sure
which one) may be turned off without notifying audio side about such change.
Now, from audio side codec is still present on the link and thus counted as
active. And thus verbs are still being sent to it - timing out in consequence.
Problem seems to exist since SKL and isn't strictly tied to ICL. The only
reason it is visible now, is probably of yet another issue present for ICL
platforms. We need to fix the root cause though. GFX guys must be engaged and
comment on this.
