[SRU][J/OEM-5.14][PATCH 1/1] ALSA: hda/realtek: Fix mute led issue on thinkpad with cs35l41 s-codec

BugLink: https://bugs.launchpad.net/bugs/1978915

The quirk ALC287_FIXUP_CS35L41_I2C_2 needs to chain the quirk
ALC269_FIXUP_THINKPAD_ACPI, otherwise the mute led will not work if a
thinkpad machine applies that quirk.

And it will be safe if non-thinkpad machines apply that quirk since
hda_fixup_thinkpad_acpi() will check and return in this case.
