[PATCH v2 2/4] dt-bindings: iio: magnetometer: Add binding for QST QMC5883P

Add the device tree binding document for the QST QMC5883P, a 3-axis
anisotropic magneto-resistive (AMR) sensor with a 16-bit ADC that
communicates over I2C. The binding exposes the required 'compatible'
and 'reg' properties along with an optional 'vdd-supply' for the
2.5 V–3.6 V VDD rail.

+description:
+ The QMC5883P is a 3-axis anisotropic magneto-resistive (AMR) sensor with a
+ 16-bit ADC. It communicates over I2C (standard and fast modes) and is
+ targeted at compass, navigation, and industrial applications.
