[PATCH AUTOSEL 6.18-6.12] ALSA: hda: Add Lenovo Legion 7i 16IAX7 17AA3874 quirk

[Sasha Levin]

From: Kamlesh Chhetty <kamleshkc2002@xxxxxxxxx>

[ Upstream commit 6485da8579e2b0132630faa1ee2ac72ccaf01501 ]

Lenovo Legion 7i 16IAX7 systems with Realtek ALC287 codec SSID
17aa:3874 and CSC3551/CS35L41 speaker amps do not provide the
required CS35L41 _DSD properties in ACPI.

Without a quirk, cs35l41-hda fails probing the amps with missing
cirrus,dev-index / Platform not supported errors, leaving the built-in
speakers silent.

This model is similar to the already-supported 17AA386F Legion 7i
16IAX7 variant. Add the Realtek ALC287 quirk to select
ALC287_FIXUP_CS35L41_I2C_2 and add 17AA3874 to the CS35L41 property
table using the same two-amp external-boost configuration.

Tested on a Lenovo Legion 7 16IAX7 with Ubuntu 7.0.0-22-generic. Both
CSC3551 CS35L41 amps probe and bind, firmware loads, calibration
applies, built-in speaker playback works, and the cirrus,dev-index
failure is gone.

LLM Generated explanations, may be completely bogus:

The background git searches finished. They confirm:

- **No commit for `17AA3874` or "Legion 7i 16IAX7 17AA3874"** is in this
  6.18.44 tree — the quirk is still missing.
- **Related Legion audio quirks are present**, including `24b6332c2d4ff`
  (Legion 7i gen7 / SSID 386F) and `39815cdfc8d46` (386F PCI SSID
  conflict fix, Cc: stable).

That lines up with the earlier analysis: this is a sibling SSID variant
that needs the same treatment as 386F. Verdict remains **YES** for
backport to this tree.
