Subject: [PATCH 01/15] arm64: dts: qcom: ipq5424: Add default GIC address
 cells

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

  ipq5424.dtsi:961.4-964.30: Warning (interrupt_map): /soc@...cie@...00000:interrupt-map:
    Missing property '#address-cells' in node /soc@...nterrupt-controller@...0000, 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).
