Something like below?

remove all 0x4xxxxxxx from pin quirk table
rewrite the pin_config_match()
  - first, compare all pins in a quirk table with the corresponding pin 
on the machine, if all pins get a matching,
  - second, compare all pins on the machine with the corresponding pin 
in the quirk table
          if the pin is non-0x4xxxxxxx, it needs match a corresponding 
pin in the quirk table, otherwise, it return false
          if the pin is 0x4xxxxxxx, the corresponding pin in the quirk 
table is 0x4xxxxxxxx as well, it matches; if the corresponding pin in 
the quirk table is non-0x4xxxxxxx, it return false
          if the pin is 0x4xxxxxxx, and can't find the corresponding pin 
in the quirk table, it matches.
