ALSA: hda - Allow patching with any vendor/subsystem ids
In the ugly real world, there area really broken devices that don't set codec SSID correctly. In such a case, the ID can be random, thus the patching won't work reliably. For applying the patch forcibly to such a device, the driver will skip the vendor and/or subsystem ID checks when zero or a negative number is given in [codec] section.
