[ALSA] add sigmatel codec support
HDA generic driver,HDA Codec driver Add initial SigmaTel codec support for 9200 and 922x. Note that this hda patch relies on the configuration default registers to be set correctly (normally by BIOS/firmware) in order for it to set up pin widgets properly. There's a test switch in the patch so it will work with the SigmaTel reference boards that are usually plugged into a system that doesn't set the configuration default registers. It supports 2 channel analog out and line/mic in. I plan to add >2 channel support and spdif support shortly. Please apply.
