sound updates for v3.10-rc1

Mostly many small changes spread as seen in diffstat in sound/*
 directory by this update.  A significant change in the subsystem level
 is the introduction of snd_soc_component, which will help more generic
 handling of SoC and off-SoC components.
 
 Also, snd_BUG_ON() macro is enabled unconditionally now due to its
 misuses, so people might hit kernel warnings (it's a good thing for
 us).
