ALSA: hda/conexant: Fix conflicting quirk for System76 Pangolin

Browse Source 
We received a regression report for System76 Pangolin (pang14) due to
the recent fix for Tuxedo Sirius devices to support the top speaker.
The reason was the conflicting PCI SSID, as often seen.

As a workaround, now the codec SSID is checked and the quirk is
applied conditionally only to Sirius devices.
