NAK.

This information is not a binding, and it's not a property of the
interrupt controller. It's the integration of a full SoC, which should
be described full in a dtsi where it can actually be used.

The only other SoCs that have this are other sunxi variants, and I see
no reason to have them here either.

Thanks,
Mark.
