All these compatible strings point to the exact same behaviour. It was
already a mistake to have the three "ingenic,jz47[70,75,80]-intc" here;
there should have been only one, e.g. "ingenic,jz4770-intc" and the 
other
two SoCs using it as a fallback compatible.

I think you don't need to add these, and in your devicetree just use
"ingenic,jz4780-intc" as a fallback compatible.

Cheers,
-Paul
