Subject: [PATCH v3 06/10] dt-bindings: iio: accel: add interrupt-names

Add interrupt-names INT1 and INT2 for the two interrupt lines of the
sensor. Only one line will be connected for incoming events. The driver
needs to be configured accordingly. If no interrupt line is set up, the
sensor will still measure, but no events are possible.
