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.
