Thanks for your patch!

Originally, when I assumed incorrectly that dtc does not support
arithmetic, I used "nr" and "na" in the macro I proposed to mean RISC-V
("r") resp. ARM ("a") interrupt number. Apparently the names stuck,
although the second parameter now has a completely different meaning ;-)
However, as the NCEPLIC does support interrupt flags, unlike the SiFive
PLIC, there is no need to have the flags parameter in the macro.

The rest LGTM.
