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.
