[PATCH alsa-ucm-conf 2/3] cht-bsw-rt5672: Add support for controlling speaker- and mic-mute LEDs

[Hans de Goede]

Add support for controlling speaker- and mic-mute LEDs using the new
snd_ctl_led kernel module for generic mute LED control.

Tested on a Thinkpad 10 tablet which has a detachable USB keyboard with
a speaker mute LED embedded in the volume-mute button and a mic mute
LED embedded in the mic-mute button.
