baytrail: HDA function disable workaround

Parts of the audio path are common between the HDA and LPE.
However, those parts are power-controlled by the D-state of
the HDA device. Therefore, one cannot put the HDA into D3Hot
because those audio paths will be shutdown.

BUG=chrome-os-partner:22871
BRANCH=None
TEST=Built and booted through depthcharge. Disabling HDA still
     causes a shutdown when performing warm reset, however I
     was able to verify the magic sequence was being performed.
