ASoC: TWL4030: Change the common playback volume controls

Browse Source 
Add Playback volume controls for all four DACs.
All four paths has three levels of volume controls:
Digital Fine gain, Digital Coarse gain, Analog gain.

The controls are named to reflect their connection to the DACs.
Per DAC volume can be performed, if needed:
amixer sset 'DAC1 Analog'  5,10
DACL1 analog gain to 5
DACR1 analog gain to 10
