ASoC: Updates for v4.2

Browse source 
The big thing this release has been Liam's addition of topology support
 to the core.  We've also seen quite a bit of driver work and the
 continuation of Lars' refactoring for component support.
 
  - Support for loading ASoC topology maps from firmware, intended to be
    used to allow self-describing DSP firmware images to be built which
    can map controls added by the DSP to userspace without the kernel
    needing to know about individual DSP firmwares.
  - Lots of refactoring to avoid direct access to snd_soc_codec where
    it's not needed supporting future refactoring.
  - Big refactoring and cleanup serieses for the Wolfson ADSP and TI
    TAS2552 drivers.
  - Support for TI TAS571x power amplifiers.
  - Support for Qualcomm APQ8016 and ZTE ZX296702 SoCs.
  - Support for x86 systems with RT5650 and Qualcomm Storm.
