dt-bindings:iio:magnetometer:fsl,mag3110: txt to yaml conversion

Dropped a few bits of help text in here that didn't seem to add anything
that wasn't fairly obvious.  Otherwise simple format conversion

-* FREESCALE MAG3110 magnetometer sensor
-
-Required properties:
-
-  - compatible : should be "fsl,mag3110"
-  - reg : the I2C address of the magnetometer
-
-Optional properties:
-
-  - interrupts: the sole interrupt generated by the device
-
-  Refer to interrupt-controller/interrupts.txt for generic interrupt client
-  node bindings.
-
-  - vdd-supply: phandle to the regulator that provides power to the sensor.
-  - vddio-supply: phandle to the regulator that provides power to the sensor's IO.
-
-Example:
-
-magnetometer@e {
-	compatible = "fsl,mag3110";
-	reg = <0x0e>;
-	pinctrl-names = "default";
-	pinctrl-0 = <&pinctrl_i2c3_mag3110_int>;
-	interrupt-parent = <&gpio3>;
-	interrupts = <16 IRQ_TYPE_EDGE_RISING>;
-};
