PL -> PS Interrupt device tree mapping bug in Petalinux 2018.2

If you use a concatenation block in the PL to send interrupts to the PS-side, make sure you do not have any gaps with empty connections. If you do petalinux will generate the wrong interrupt # in the device tree and the system will fail in mysterious ways 

 

Would be nice if Xilinx could fix, as the device tree generation TCL-land is not fun to go digging in
