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.

-Required properties:
-
-  - compatible: should contain one of
-    * "fsl,mma8451"
-    * "fsl,mma8452"
-    * "fsl,mma8453"

-
-  - 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:
