ams AG AS62XX temperature sensor driver

Required properties:
        - compatible: must be "ams,as62xx"
        - reg: I2C 7-bit address for the device
                possible values: 0x44, 0x45, 0x46, 0x47, 0x48, 0x49, 0x4a, 0x4b
        - interrupt-parent: should be the handle for the interrupt controller
        - interrupts: the sole interrupt generated by the device

        Refer to interrupt-controller/interrupts.txt for generic
        interrupt client node bindings.

Example:

as62xx@0x44 {
        compatible = "ams,as62xx";
        reg = <0x44>;
        interrupt-parent = <&gpio>;
        interrupts = <17 1>;
        status = "okay";
};
