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.

Most of the nodes in this DT has compatible and reg at the beginning. For clarity would be good to keep the rule for this one as well.
