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.
