arm64: dts: toshiba: tmpv7708: Add default GIC address cells

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

  tmpv7708.dtsi:503.4-507.28: Warning (interrupt_map): /soc/pcie@28400000:interrupt-map:
    Missing property '#address-cells' in node /soc/interrupt-controller@24001000, 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)
