ALSA: hda - Add a conexant codec entry to let mute led work

commit 3f8809499bf02ef7874254c5e23fc764a47a21a0 upstream.

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.
