[U-Boot] [PATCH] arm: imx: add tzic interrupt controller for imx53

[linux-kernel-dev at beckhoff.com <linux-kernel-dev@beckhoff.com>]

From: Patrick Bruenn <p.bruenn@beckhoff.com>

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 at 50000000/serial at 53fc0000
arch/arm/dts/imx53-cx9020.dtb: Warning (interrupts_property): Missing interrupt-parent for /soc/aips at 50000000/ccm at 53fd4000
arch/arm/dts/imx53-cx9020.dtb: Warning (interrupts_property): Missing interrupt-parent for /soc/aips at 50000000/gpio at 53fe4000
arch/arm/dts/imx53-cx9020.dtb: Warning (interrupts_property): Missing interrupt-parent for /soc/aips at 60000000/sdma at 63fb0000
arch/arm/dts/imx53-cx9020.dtb: Warning (interrupts_property): Missing interrupt-parent for /soc/aips at 60000000/ethernet at 63fec000

Fix this by adding a node for the tzic interrupt controller.
