[PATCH v2 2/3] HID: elan: Set default_trigger for the mute LED

[Hans de Goede]

The mute LED should be automatically turned on/off based
on the audio-card's mixer settings.

Add the standardized default-trigger name for this, so that the alsa
code can turn the LED on/off as appropriate (on supported audio cards).
