dt-bindings:iio:accel:bosch,bma180: txt to yaml format conversion.

One question in here is whether we want to constrain the number of
interrupts.  Some parts definitely only have 1 such pin, and others
2 pins but I can not find information on the bma254.

Oleksandr's email address is bouncing so I've listed myself as
maintainer for this binding until someone else steps up.

-Required properties:
-
-  - compatible : should be one of:
-    "bosch,bma023"
-    "bosch,bma150"
-    "bosch,bma180"
-    "bosch,bma250"
-    "bosch,bma254"
-    "bosch,smb380"
-  - reg : the I2C address of the sensor
-  - vdd-supply : regulator phandle connected to the VDD pin
-  - vddio-supply : regulator phandle connected to the VDDIO pin
-
-Optional properties:
-
-  - interrupts : interrupt mapping for GPIO IRQ, it should by configured with
-               flags IRQ_TYPE_LEVEL_HIGH | IRQ_TYPE_EDGE_RISING
-               For the bma250 the first interrupt listed must be the one
-               connected to the INT1 pin, the second (optional) interrupt
-               listed must be the one connected to the INT2 pin.
-
-Example:
-
-bma180@40 {
-       compatible = "bosch,bma180";
-       reg = <0x40>;
-       interrupt-parent = <&gpio6>;
-       interrupts = <18 (IRQ_TYPE_LEVEL_HIGH | IRQ_TYPE_EDGE_RISING)>;
-};
