ASoC: Updates for v4.1
More updates for v4.1, pretty much all drivers:
- Lots of cleanups from Lars, mainly moving things from the CODEC level
to the card level.
- Continuing improvements to rcar from Morimoto-san, pcm512x from
Howard and Peter, the Intel platforms from Vinod, Jie, Jin and Han,
and to rt5670 from Bard.
- Support for some non-DSP Qualcomm platforms, Google's Storm
platform, Maxmim MAX98925 CODECs and the Ingenic JZ4780 SoC.
