I agree this looks odd. I took it from Russel's ICU mapping:
http://lists.infradead.org/pipermail/linux-arm-kernel/2017-February/489040.html

The driver does not use this interrupt (yet?). I'm not sure what is this
interrupt exact configuration...

Do you want me to remove this from the documentation (and device trees)?

Thanks,
Antoine
