3.10-stable review patch. If anyone has any objections, please let me know.
------------------ From: Takashi Iwai <ti...@suse.de> commit d045c5dc43d829df9f067d363c3b42b14dacf434 upstream. Some VIA codecs like VT1708S have Mic boost amps in the mic pins but they aren't exposed in the capability bits. In the past driver code, we override the pin caps and create mic boost controls forcibly. While transition to the generic parser, we lost the mic boost controls although the pin caps are still overridden, because the generic parser code checks the widget caps, too. So this patch adds a new helper function to allow the override of the given widget capability bits, and makes VIA codecs driver to add the missing input-amp capability bit.
