ALSA: hda/realtek: Fix quirk matching for Legion Pro 7

Browse source

commit 0f3a822ae2 upstream.

The recent cleanup of the quirk table entries with the codec ID
matching caused a regression on some Lenovo Legion 7 models with PCI
SSID 17aa:386f: it assumed wrongly as if the codec SSID on the machine
were also 17aa:386f, but in this case, it was 17aa:38a8.  This made
the binding with a wrong sub-codec, instead of TAS2781, the Cirrus
codec was bound.

For addressing the regression, correct the quirk entry to the right
value 17aa:38a8.

Note that this makes the entry appearing in an unsorted position.
This exception is needed because the entry must match before the PCI
SSID 17aa:386f.

Also there is another entry for 17aa:38a8, but the latter is for PCI
SSID matching while the new entry is for the codec SSID matching.
