dt-bindings:iio:magnetometer:asahi-kasei,ak8974: txt to yaml format conversion

Browse Source 
Simple conversion.  I have pruned descriptions that did not add much useful
detail.  Note that the mount-matrix description will form part of a generic
IIO binding.  No need to repeat that in every driver that uses it.

* Asahi Kasei AK8974 magnetometer sensor
Required properties:
- compatible:
* "asahi-kasei,ak8974"
* "alps,hscdtd008a"
- 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@f {
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>;
};
