Fix sound on ASUS Transformers

Merge series from Svyatoslav Ryhel <clamor95@gmail.com>:

- add quirk for headset detection used by some T30 devices
  (ASUS Transformers, LG Optimus 4X HD and Vu);
- add RT5631 and MAX9808x machine drivers
- update bindings

---
Changes from v1
- fm34 dropped for re-work
- quirk for headset detection and rt5631 bringup splitted
- minor adjustments in binding updates
- improvement of rt5631 rate asignment
---
