Subject: [PATCH] ALSA: hda/realtek: Fix Legion 7 16ITHG6 speaker amp binding

The Lenovo Legion 7 16ITHG6 uses codec SSID 17aa:3855, but its PCI
SSID is 17aa:3811.  The latter is now also used by the Legion S7 15IMH05
quirk, which is matched before codec SSID fallback and incorrectly
routes Legion 7 16ITHG6 machines to ALC287_FIXUP_LEGION_15IMHG05_SPEAKERS.

That fixup does not bind the CLSA0101 CS35L41 companion amplifiers,
making the built-in speakers silent even though playback appears to be
active.

Add a codec SSID quirk for 17aa:3855 before the conflicting PCI SSID
quirk so that the Legion 7 16ITHG6 uses ALC287_FIXUP_LEGION_16ITHG6.
This restores CS35L41 firmware loading and binds both speaker
amplifiers.
