Pull sound updates from Takashi Iwai:
 "It was another busy development cycle, and the majority of changes are
  found in ASoC side. Below are Some highlights.

  ASoC core:
   - Lots of core cleanups and refactorings, still on-going work by
     Morimoto-san

  ASoC drivers:
   - Continued work on cleaning up and improving the Intel SOF stuff,
     along with new platform support including SoundWire

   - Fixes to make the Marvell SSPA driver work upstream

   - Support for AMD Renoir ACP, Dialog DA7212, Freescale EASRC and
     i.MX8M, Intel Elkhard Lake, Maxim MAX98390, Nuvoton NAU8812 and
     NAU8814 and Realtek RT1016.

  USB-audio:
   - Improvement for sync and implicit feedback streams with the more
     accurate frame size calculation and full-duplex support

   - Support for RME Babyface Pro and Prioneer DJ DJM

  HD-audio:
   - Fixes for Mic mute LED on HP machines

   - Re-enable support of Intel SST driver for SKL/KBL platforms

  FireWire:
   - Lots of refactoring, add support for RME FireFace and MOTU
     UltraLite-mk3"
