Subject: [PATCH v2 03/14] dt-bindings: iio: accel: bosch,bma220 change irq
 type

Set the interrupt type to rising edge instead of high level.

Quoting from the datasheet:

 "If at least one of the configured conditions applies, an interrupt
 (logic ‘1’) is issued through the INT pin of the sensor."

The old code did not request an irq line via devm_request_threaded_irq()
so there is no backward compatibility that would be affected by this
change.
