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.
