ASoC: Updates for v4.4 

Not much core work here, a few small tweaks to interfaces but mainly the
 changes here are driver ones.  Highlights include:
 
  - Updates to the topology userspace interface
  - Big updates to the Renesas support from Morimoto-san
  - Most of the support for Intel Sky Lake systems.
  - New drivers for Asahi Kasei Microdevices AK4613, Allwinnner A10,
    Cirrus Logic WM8998, Dialog DA7219, Nuvoton NAU8825 and Rockchip
    S/PDIF.

from the simplification of a new card support and the capability of the wide

I2S/PCM type sound cards, such as S/PDIF audio and HDMI audio, as long
as the driver has been properly upgraded.
