ASoC: cs35l45: Analog PCM Volume and Amplifier Mode controls
Adds "Analog PCM Volume" control with supported values
0 = 10dB,1 = 13dB,2 = 16dB and 3 = 19dB.
The amplifier can operate either in Speaker Mode or Receiver Mode
as configured by the user. Speaker Mode has four gain options
to support maximum amplifier output amplitude for loud
speaker application. Receiver Mode has further optimized
noise performance while maintaining sufficient output to support
phone receiver application. While configured in Receiver Mode,
the analog PCM Volume control is disabled and
the analog gain is fixed to 1dB.
