Title: alsa: Add support for mixer element indexes

Some drivers register multiple mixer elements with the same name.
Make the plugin aware of mixer element indexes to tell such mixer
elements apart.

Tested on soundcard with two "PCM" mixer elements.

Verified to work:
- switching between elements with same name
- switching between elements with different names
- controlling elements with unique name
- saving and restoring configuration
- reading v3.4 configuration (defaults to the first mixer element matching old configuration)
