[ALSA] Add speaker pin sequencing to hda_codec.c:snd_hda_parse_pin_def_config()

Browse source 
Some verb tables (such as an Asus VT sent by IDT) contain only speaker
outs in the default pin configs, and no line-outs. In such a case the
speaker sequence numbers have to be used to order the speaker out
pins, just as is being done for line-out pins. Then, when speaker-outs
are copied to line-outs, the line-outs will be ordered properly.
