[SRU][B/OEM-B/D/E][PATCH 1/1] ALSA: hda - Add a conexant codec entry to let mute led work

BugLink: https://bugs.launchpad.net/bugs/1837963

This conexant codec isn't in the supported codec list yet, the hda
generic driver can drive this codec well, but on a Lenovo machine
with mute/mic-mute leds, we need to apply CXT_FIXUP_THINKPAD_ACPI
to make the leds work. After adding this codec to the list, the
driver patch_conexant.c will apply THINKPAD_ACPI to this machine.
