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

Browse source 
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.

* Bosch BMA023 / BMA150/ BMA180 / BMA25x / SMB380 triaxial acceleration sensor

http://ae-bst.resource.bosch.com/media/products/dokumente/bma250/bst-bma250-ds002-05.pdf
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)>;
};
