[ALSA] hda-codec - More fix-up for auto-configuration
In some cases, the BIOS sets up only the HP pins with different assoc and sequence numbers, e.g. on FSC Esprimo with ALC262. This patch adds a fix-up for such a case. When multiple HPs are defined and no line-outs is found, the configurator tries to re-assign some pins from HP list to line-out, judging from the sequence number.
