Merge tag 'asoc-v4.9' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-next

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.

-The platform device problem
----------------------------
-DSA is currently implemented as a platform device driver which is far from ideal
-as was discussed in this thread:
-
-http://permalink.gmane.org/gmane.linux.network/329848
-
-This basically prevents the device driver model to be properly used and applied,
-and support non-MDIO, non-MMIO Ethernet connected switches.
-
-Another problem with the platform device driver approach is that it prevents the
-use of a modular switch drivers build due to a circular dependency, illustrated
