Changes since v5:
    Remove sub node "sound" and "mediatek,platform", "mediatek,dptx-codec",
    "mediatek,hdmi-codec" properties. Let dsp node as an individual node and
    sound card has phandle of this dsp node per discussion in 
    https://github.com/thesofproject/linux/pull/3239

Changes since v4:
  - remove patch 1 with clocks as it will be reviewed and merged to SOF tree.
    https://github.com/thesofproject/linux/pull/3237
  - refine DT file binding files with Rob's comments.
