This reverts 'commit 3708d5e082c3 ("drm/i915: start adding dp mst audio")'
because it breaks MST multi-monitor setups on some platforms.

Bug: https://bugs.freedesktop.org/show_bug.cgi?id=97907

Oh, I hope

commit f931894194b9395313d1c34f95ceb8d91f49790d
Author: Pandiyan, Dhinakaran <dhinakaran.pandiyan@intel.com>
Date:   Wed Sep 21 13:02:48 2016 -0700

    drm/i915/dp: DP audio API changes for MST

doesn't have a (functional) dependency on the reverted commit?

BR,
Jani.

already exposed to the audio drivers and should not depend on the
reverted MST audio enabling patch.
