ALSA: hda: Code refactoring snd_hda_pick_fixup()

Browse source 
This contains a slight code refactoring of snd_hda_pick_fixup():
- Unify the ID setup
- Unify the debug print message
- Use snd_pci_quirk_lookup_id() for the codec SSID matching

Mostly for simplifying the code flow but also it makes easier to add
the codec alias handling in the upcoming patch.
