ALSA: Increase components array size
Increase the card components[] (and thus snd_card_info.components[], too) array size from 80 to 128 chars so that more strings can be stored. The 80 chars aren't enough for more than 2 HD-audio codecs, and this hits an ugly snd_BUG() as reported by Wu Fegguang for HP 2230s. The control protocol number is increased to 2.0.6 as well, in case it matters.
