arm64: dts: qcom: sc8180x: Add default GIC address cells

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

  sc8180x.dtsi:1743.4-1746.30: Warning (interrupt_map): /soc@0/pcie@1c00000:interrupt-map:
    Missing property '#address-cells' in node /soc@0/interrupt-controller@17a00000, 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).
