dt-bindings:iio:accel:fsl,mma8452: txt to yaml conversion.

Simple binding so mostly straight forward to convert.
Original binding was unclear on how many interrupts there are.
The device has two such lines, whilst I believe the driver currently
only uses one at a time.  The binding should allow both to be specified.

Freescale MMA8451Q, MMA8452Q, MMA8453Q, MMA8652FC, MMA8653FC or FXLS8471Q
triaxial accelerometer
Required properties:
- compatible: should contain one of
* "fsl,mma8451"
* "fsl,mma8452"
* "fsl,mma8453"
* "fsl,mma8652"
* "fsl,mma8653"
* "fsl,fxls8471"
- reg: the I2C address of the chip
Optional properties:
- interrupts: interrupt mapping for GPIO IRQ
- interrupt-names: should contain "INT1" and/or "INT2", the accelerometer's
interrupt line in use.
- vdd-supply: phandle to the regulator that provides vdd power to the accelerometer.
- vddio-supply: phandle to the regulator that provides vddio power to the accelerometer.
Example:
mma8453fc@1d {
compatible = "fsl,mma8453";
reg = <0x1d>;
interrupt-parent = <&gpio1>;
interrupts = <5 0>;
interrupt-names = "INT2";
};
