When using interrupts property, a global interrupt controller needs to be added to avoid warnings when compiling device-tree:
arch/arm/dts/at91-sama5d2_xplained.dtb: Warning (interrupts_property): /ahb/apb/timer@f800c000: Missing interrupt-parent
Add AIC node as the sama5d2 global interrupt controller.
