Colibri modules need to be powered using the power pins 3V3 and AVDD_AUDIO. Add fixed regulators which represent this power rails. Potentially, those power rails could be switched on a carrier board. A carrier board device tree could add a own regulator with a GPIO, and reference that regulator in a vin-supply property of those new module level system regulators. This also synchronize the name of the +3.3V regulator with the one used in the Colibri VF50/VF61 device tree.
