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.
