dt-bindings: iio: light: vcnl4000: add regulators

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 open drain interrupt line, to ensure the sensor
is powered on before proceeding with setup.
