[PATCH 1/2] ARM: dts: vf-colibri: remove container node of regulators

[Stefan Agner]

Drop the fake simple-bus container 'regulators' and put the
regulators directly under the root node. This also makes the
artificial 'reg' properties superfluous.

[PATCH 2/2] ARM: dts: vf-colibri: add supply regulators

[Stefan Agner]

Colibri modules need to be powered using the power pins 3V3 and
AVDD. 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.

Applied both, thanks.
