dts: arm: nxp: s32: add `#address-cells` to interrupt provider

Add `#address-cells = <0>;` to interrupt provider nodes in
the NXP S32 device tree to resolve warnings: e.g.
Warning (interrupt_provider): /soc/interrupt-controller@47800000: Missing
Warning (interrupt_provider): /soc/siul2@40520000/eirq0@40520010: Missing

This ensures compliance with device tree specifications and
eliminates build warnings.
