[PATCH V2] ALSA: hda/realtek: Add subwoofer quirk for Acer Predator G9-593

[José Relvas <josemonsantorelvas@xxxxxxxxx>]

The Acer Predator G9-593 has a 2+1 speaker system which isn't probed correctly.
This patch adds a quirk with the proper pin connections.

Note that I do not own this laptop, so I cannot guarantee that this fixes the issue.
Testing was done by other users here:
https://discussion.fedoraproject.org/t/-/118482

This model appears to have two different dev IDs...

- 0x1177 (as seen on the forum link above)
- 0x1178 (as seen on https://linux-hardware.org/?probe=127df9999f)

I don't think the audio system was changed between model revisions, so the patch
applies for both IDs.
