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.

Add a MAINTAINERS entry for the QSTCORP QMC5883P devicetree binding.

+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.
