[PATCH 3/3] dt-bindings: i2c: nvidia,tegra20-i2c: define power-domains top-level

[Krzysztof Kozlowski]

Properties are expected to be defined in top-level "properties:" block
and further customized in "if:then:".  Only one variant has power
domains, so add respective top-level property and disallow it for other
devices.
