iio: magn: DT bindings for AK8974
This adds device tree bindings for the AK8974 magnetometer, similar to those for the AK8975.

+* Asahi Kasei AK8974 magnetometer sensor
+
+Required properties:
+
+- compatible : should be "asahi-kasei,ak8974"
+- reg : the I2C address of the magnetometer
+
+Optional properties:
+
+- avdd-supply: regulator supply for the analog voltage
+ (see regulator/regulator.txt)
+- dvdd-supply: regulator supply for the digital voltage
+ (see regulator/regulator.txt)
+- interrupts: data ready (DRDY) and interrupt (INT1) lines
+ from the chip, the DRDY interrupt must be placed first.
+ The interrupts can be triggered on rising or falling
+ edges alike.
+- mount-matrix: an optional 3x3 mounting rotation matrix
+
+Example:
+
+ak8974@0f {
+ compatible = "asahi-kasei,ak8974";
+ reg = <0x0f>;
+ avdd-supply = <&foo_reg>;
+ dvdd-supply = <&bar_reg>;
+ interrupts = <0 IRQ_TYPE_EDGE_RISING>,
+ <1 IRQ_TYPE_EDGE_RISING>;
+};
