sound fixes for 4.6-rc1

Browse Source 
The previous pull request introduced a few WARN_ON() for Intel
 HD-audio HDMI.  Indeed it caught bugs, and now users get annoyed.
 So this request came up: a collection of small fixes to paper over
 the inconsistencies on (mostly) old Intel chipsets.
 
 In addition, a trivial USB-audio quirk is included, too.
