ASoC: Updates for v4.9
Apart from the cleanups done by Morimoto-san this has very much been a
driver focused release with very little generic change:
- A big factoring out of the simple-card code to allow it to be shared
more with the rcar generic card from Kuninori Morimoto.
- Removal of some operations duplicated on the CODEC level, again by
Kuninori Morimoto.
- Lots more machine support for x86 systems.
- New drivers for Nuvoton NAU88C10, Realtek RT5660 and RT5663.
