V2:
- Drops redundant verbage "Defintion of the" from each of the newly defined
  regulators - Krzysztof Kozlowski
- Adds Acked-by: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org>
- "description: thing described" to the same line in new additions
  following the established way of doing it in this file - bod

V1:
The imx412 has three regulators which depending on platform may need to be
individually enabled.

- dovdd
- avdd
- dvdd

Existing code for an Intel platform doesn't appear to need to enable these
rails directly. On my reference hardware, a Qualcomm Thundercomm RB5 some
of these rails do need to be enabled individually.

Add in the above named rails as optional in the YAML in the first patch
along with code to switch them on in the second patch.

Existing imx412 users should get dummy regulators populated which the
regulator_bulk_enable()/regulator_bulk_disable() code can safely ignore.
