ASoC: Intel: avs: Update stream status in a separate thread
Function snd_pcm_period_elapsed() is part of sequence servicing HDAudio
stream IRQs. It's called under Global Interrupt Enable (GIE) disabled -
no HDAudio interrupts will be raised. At the same time, the function may
end up calling __snd_pcm_xrun() or snd_pcm_drain_done(). On the
avs-driver side, this translates to IPCs and as GIE is disabled, these
will never complete successfully.
Improve system stability by scheduling stream-IRQ handling in a separate
thread.
