ALSA: hda: Add Lenovo Legion 7i 16IAX7 17AA3874 quirk

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.
