[PATCH v3 2/4] dt-bindings: iio: accel: adi,adxl367: add interrupt-names

The ADXL367 has two independent interrupt output pins, INT1 and INT2,
either of which may be wired to the host. Allow the interrupt line that
is connected to be described by adding an optional interrupt-names
property accepting "INT1" and/or "INT2", and permit a second interrupt
entry. interrupt-names is kept optional so existing device trees that
only specify a bare interrupts property remain valid.
