ASoC: Updates for v4.10
There's been a few bits of framework work this time around and quite a
lot of cleanups and improvements to existing code:
- Support for stereo DAPM controls from Chen-yu Tsai.
- Some initial work on the of-graph sound card from Morimoto-san, the
main bulk of this is currently in binding review.
- Lots of Renesas cleanups from Morimoto-san and sunxi work from
Chen-yu Tsai.
- regmap conversions of the remaining AC'97 drivers from Lars-Peter
Clausen.
- A new version of the topology ABI from Mengdong Lin.
- New drivers for Cirrus Logic CS42L42, Qualcomm MSM8916-WCD, and Realtek
RT5665.
