Changes since v2:

- Added platform data support for Mic bias voltage and source
- Used DAPM for DAC source selection
- Other minor improvements
---
Changes since v1:

- Made extensive use of DAPM throughout the driver
- Removed LDO, DMIC and other non used controls
- Corrected names for many controls
- Other minor improvements
