On Apollolake, with stress test warm reboot, audio card
was not getting enumerated after reboot. This was a
spurious issue happening on Apollolake. HW codec and
HD audio controller link was going out of sync for which
there was a fix in i915 driver but was not getting invoked
for BXT. Extending this fix to BXT as well.

Tested on apollolake chromebook by stress test warm reboot
with 2500 iterations.

Bspec: 21829

R-B stands.

Btw, it would be easier to spot this patch and pick this up for merging
if you did not send this as a reply. I guess that's okay this time?
Also, a minor nitpick, "drm/i915/audio" would have been a more
appropriate prefix for the patch subject.

Thanks for the patch and review, pushed to dinq, with the patch title
amended.

Immediately after pushing I realized that this should have been Cc:
stable. Joonas, after v4.17-rc1 is out and you've rebased
drm-intel-fixes on it, please cherry-pick this one with Cc: stable
added.

Thanks,
Jani.
