ALSA: hda - remove no physical connection pins from pin_quirk table

To cleanup the pin_quirk table:
 - rewrite the pin_config_match(), comparing all pins on the machine
   with the corresponding pins in the quirk table.
 - remove all 0x4xxxxxxx pin configurations from pin_quirk table
 - after removing the 0x4xxxxxxx pin configurations, some pin tables
   are exactly same, so removing the redudant pin tables.
