[PATCH v4 1/7] dt-bindings: iio: light: vcnl4000: add regulators

[Erikas Bitovtas]

These sensors can accept 2 supplies - one for the sensor and one for IR
LED [1]. Add supply properties for the sensor - 2 for the sensors and
one external, for their I2C bus, to ensure the sensor is powered on
before proceeding with setup.
