dt-bindings: iio: magnetometer: Add Voltafield AF8133J 



Voltafield AF8133J is a simple magnetometer sensor produced by Voltafield
Technology Corp, with dual power supplies (one for core and one for I/O)
and active-low reset pin.

The sensor has configurable range 1.2 - 2.2 mT and a software controlled
standby mode.

Add a device tree binding for it.

    description:

      A signal for active low reset input of the sensor. (optional; if not

      used, software reset over I2C will be used instead)
