ALSA: hda - Add a new quirk match based on default pin configuration
Normally, we match on pci ssid only. This works but needs new code for every machine. To catch more machines in the same quirk, let's add a new type of quirk, where we match on 1) PCI Subvendor ID (i e, not device, just vendor) 2) Codec ID 3) Pin configuration default If all these three match, we could be reasonably certain that the quirk should apply to the machine even though it might not be the exact same device.
