This is not right. Since this node has 2 interrupt-cells, you need 2 
entries for the child-interrupt specifier. You also need to set 
#address-cells to 0 and set the mask to mask out the 2nd cell.

Then again, there is not any real translation happening here, so perhaps 
you don't need this at all.
