arm64: dts: imx8dxl: Add default GIC address cells

Add missing address-cells 0 to GIC interrupt node to silence W=1
warning:

  imx8dxl-ss-hsio.dtsi:45.3-48.27: Warning (interrupt_map): /bus@5f000000/pcie@5f010000:interrupt-map:
    Missing property '#address-cells' in node /interrupt-controller@51a00000, using 0 as fallback

Value '0' is correct because:
1. GIC interrupt controller does not have children,
2. interrupt-map property (in PCI node) consists of five components and
   the fourth component "parent unit address", which size is defined by
   '#address-cells' of the node pointed to by the interrupt-parent
   component, is not used (=0)
