ASoC: dt-bindings: tlv320adc3xxx: Add MICBIAS-as-GPO properties 



Add properties for configuring the MICBIAS pins as general purpose
outputs, with some limitations: The voltage on the pin when activated
may be set using another property to 2.0 V, 2.5 V or AVDD.
When deactivated the pin will float.
