ALSA: Increase components array size

Browse Source 
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.
