WIP: Rename main sound card
In order to be able to upstream a machine-specific ALSA UCM config (which must be named after the sound card), we can't use the codec name as other devices with different requirements/configurations may use the same codec.
Renaming the sound card to
Librem5 ensures we don't collide with other
potential wm8962 users and can use a unique name for our UCM config.
