sound fixes for 4.6-rc2 

A collection of small fixes:
 - A fix in ALSA timer core to avoid possible BUG() trigger
 - A fix in ALSA timer core 32bit compat layer
 - A few HD-audio quirks for ASUS and HP machines
 - AMD HD-audio HDMI controller quirks
 - Fixes of USB-audio double-free at some error paths
 - A fix for memory leak in DICE driver at hotunplug
