sound updates #2 for 4.7-rc1

This is the second update round for 4.7-rc1.  Most of changes are
 about the pending ASoC updates and fixes, including a few new
 drivers.  Below are some highlights:
 
 ASoC:
 - New drivers for MAX98371 and TAS5720
 - SPI support for TLV320AIC32x4, along with the module split
 - TDM support for STI Uniperf IPs
 - Remaining topology API fixes / updates
 
 HDA:
 - A couple of Dell quirks and new Realtek codec support
