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.

Typo and sounds like a dependency between properties:
dependencies:
