[PATCH v2] ARM: dts: r9a06g032: Add #address-cells in the GIC node

[Herve Codina (Schneider Electric)]

When checking dts involving the r9a06g032.dtsi file, the following kind
of warnings are reported:
   Missing property '#address-cells' in node xxx, using 0 as fallback

Indeed, #address-cells is not present in the GIC interrupt controller
node.

Fix it adding the missing property.

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

No functional change.
