ARM: dts: vf-colibri: add basic supply regulators
Colibri modules need to be powered using the power pins 3V3 and
AVDD. Add fixed regulators which represent this power rails.
Potentially, those power pins could be switched on a module carrier
board. A carrier board device tree could add a vin-supply property
and define a own regulator.
