sound fixes for 3.11-rc2

Except for a slightly big OMAP changes, all rest are small, mostly
 boring changes; all either 3.11 regression fixes or stable materials.
 
 - ASoC OMAP fixes due to non-DT OMAP4 removals
 - Other ASoC driver changes (sglt5000, wm8978, wm8948, samsung)
 - Fix missing locking for snd_pcm_stop() calls in many drivers
 - Fix the blocking request_module() in OSS sequencer
 - Fix old OSS vwsnd driver builds
 - Add a new HD-audio HDMI codec ID
