ec/lenovo/h8: Fix mute LEDs

thinkpad_acpi expects a SSMS method to turn on/off the mute LED
    and a MMTS method to turn on/off the microphone mute LED. With
    these methods implemented the driver can correctly sync the LEDs
    with the corresponding statuses.

There seems to be two different bits to mute the audio in the
    Lenovo H8 EC:
     * AMUT, used internally (for example to disable the audio before
        entering S3).
     * ALMT, controllable by the OS, which also toggles the mute LED
        (if present).

Tested on a X220T and on a X201.
