All NVIDIA Tegra SoCs have a core power domain where majority of hardware
blocks reside. Add binding for the core power domain.

My bot found errors running 'make dt_binding_check' on your patch:

yamllint warnings/errors:

dtschema/dtc warnings/errors:
/builds/robherring/linux-dt-review/Documentation/devicetree/bindings/power/nvidia,tegra20-core-domain.yaml: properties:power-supply: '$ref' is not one of ['description', 'deprecated']
/builds/robherring/linux-dt-review/Documentation/devicetree/bindings/power/nvidia,tegra20-core-domain.yaml: ignoring, error in schema: properties: power-supply
warning: no schema found in file: ./Documentation/devicetree/bindings/power/nvidia,tegra20-core-domain.yaml

See https://patchwork.ozlabs.org/patch/1451596

This check can fail if there are any dependencies. The base for a patch
series is generally the most recent rc1.

If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure 'yamllint' is installed and dt-schema is up to
date:

pip3 install dtschema --upgrade

Please check and re-submit.
