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.
