ALSA: hda - Add fixup for MacBook Air 6,1 and 6,2 with CS4208 codec

This patch adds the default pin configuration and some init verbs for setting COEFs, in addition to the correction of input pin AMP caps for MacBook Air 6,1 and 6,2. With these changes, the headphone jack detection starts working properly.
