There isn't one. The existing "opal-interrupts" from day one was a bit
weird anyway, it's not a proper "interrupts" property to begin with,
but it's unfixable now. Also I don't think there's a generic way to
name interrupts either.

So for this specific case, just adding a new prop with a string-list
matching 1:1 the entries in "opal-interrupts" is the most logical
choice.

Cheers,
Ben.
