This is part of the analog side of the codec. Representing it as a
standalone amp is inaccurate. Here's what I have to add it to the codec:

DT binding patch:
https://github.com/wens/linux/commit/ca6360b9788b8495daff658280845683ff401441

Driver patch:
https://github.com/wens/linux/commit/17a91e45d62d370bb2350753be6db86eaf824a5e

DT fixup:
https://github.com/wens/linux/commit/df7c2b26d1a66790237ca25e8cc135c237cd8236

As mentioned on IRC, I will pick up this series incorporating some extra
changes.

Thanks
ChenYu
