[PATCH v2 1/4] dt-bindings: iio: accel: bma255: Add interrupt-names

[Stephan Gerhold <stephan@gerhold.net>]

The binding already allows specifying both interrupt pins, but there
is currently no way to describe a board where (for whatever reason)
only INT2 is connected. Make it possible to use "interrupt-names"
to make it explicit which interrupt pin is meant in the interrupts.

Changes in v2:
  - Add "Without interrupt-names, ..." to "interrupts" description
    to clarify that ordering of interrupts can be relaxed if
    interrupt-names is used.
