Since commit 999a78d5cf00 ("scripts/dtc: Update to upstream version
v1.4.5-3-gb1a60033c110")
dtc warns about:
arch/arm/dts/imx53-cx9020.dtb: Warning (interrupts_property): Missing
interrupt-parent for /soc/aips@50000000/serial@53fc0000
arch/arm/dts/imx53-cx9020.dtb: Warning (interrupts_property): Missing
interrupt-parent for /soc/aips@50000000/ccm@53fd4000
arch/arm/dts/imx53-cx9020.dtb: Warning (interrupts_property): Missing
interrupt-parent for /soc/aips@50000000/gpio@53fe4000
arch/arm/dts/imx53-cx9020.dtb: Warning (interrupts_property): Missing
interrupt-parent for /soc/aips@60000000/sdma@63fb0000
arch/arm/dts/imx53-cx9020.dtb: Warning (interrupts_property): Missing
interrupt-parent for /soc/aips@60000000/ethernet@63fec000
Fix this by adding a node for the tzic interrupt controller.
