StMicroelectronis vl53l1

Requires properties:
- compatible: must be "st,stmvl53l1".
- reg: I2C address of the chip.
- xsdn-gpio: gpio number connected to vl53l1 reset pin.

Optional properties:
- intr-gpio: gpio number connected to vl53l1 irq pin.
- vdd: a phandle for the regulator supplying power for vl53l1.
- pwren-gpio: gpio number use to control vl53l1 power.

Example:
	&i2c1 {
		/* ... */

		stmvl53l1: stmvl53l1@29 {
			compatible = "st,stmvl53l1";
			reg = <0x29>;
			xsdn-gpio = <19>;
			pwren-gpio = <12>;
			intr-gpio = <16>;
		};

		/* ... */
	};
