ASoC: tlv320aic31xx: configure output common-mode voltage
The tlv320aic31xx devices allow to adjust the output common-mode voltage for best analog performance. The datasheet states that the common mode voltage should be set to be <= AVDD/2. This changes allows to configure the output common-mode voltage via a DT property. If the property is absent the voltage is automatically chosen as the highest voltage below/equal to AVDD/2.
