Intersil isl29044a L/P sensor

Required properties:

 - compatible			: Should be "intersil,isl29044a".
 - reg				: i2c slave address of the device.
 - vdd-supply			: Power supply needed to power up the device.
 - vio-supply			: IO power supply needed for IO and I2C.
 - intersil,als-range		: Light Sensor als range, 0: 0-125 Lux, 1: 0-2000Lux
 - intersil,ps-lt		: proximity low threshold. The proximity interrupt
				event is governed by the high and low thresholds.
 - intersil,ps-ht		: proximity high threshold.

Example:
i2c@f9925000 { /* BLSP-1 QUP-3 */
	intersil@44 {
		compatible = "intersil,isl29044a";
		reg = <0x44>;
		vdd-supply = <&pm8110_l19>;
		vio-supply = <&pm8110_l14>;
		intersil,als-range = <1>;
		intersil,ps-lt = <30>;
		intersil,ps-ht = <50>;
	};
};
