[PATCH v8 3/7] dt-bindings: iio: accel: adxl345: add interrupt-names

Add interrupt-names INT1 and INT2 for the two interrupt lines of the
sensor.

When one of the two interrupt lines is connected, the interrupt as its
interrupt-name, need to be declared in the devicetree. The driver then
configures the sensor to indicate its events on either INT1 or INT2.

If no interrupt is configured, then no interrupt-name should be
configured, and vice versa. In this case the sensor runs in FIFO BYPASS
mode. This allows sensor measurements, but none of the sensor events.
