[RFC PATCH 1/2] dt-bindings: iio: accel: adxl345: document second interrupt

[Wolfram Sang <wsa+renesas@sang-engineering.com>]

The pinout of all the supported chips in this binding have two interrupt
pins. Document the second one, too, even though the Linux driver
currently does not support the second interrupt. Boards may have it
wired nonetheless.

Passes dt_binding_check. But uncovers another issue. See coverletter.
