4a-hal-unicens: add Fiberdyne Master Volume

Bug-AGL: SPEC-1758

As preparation before introducing UNICENS 4a plugin:
- Init volume library at first
- Add fiberdyne master volume
- Introduce commands sent by control messages
- Removes outdated controls
- Known issue: turn ALSA volume above "93" to hear some sound
