hw/arm/virt: Fix devicetree warning about the GIC node 

The GICv3 bindings requires a #msi-cells property for the ITS node. Fix
the corresponding dt-validate warning:

  interrupt-controller@8000000: msi-controller@8080000: '#msi-cells' is a required property
  From schema: linux/Documentation/devicetree/bindings/interrupt-controller/arm,gic-v3.yaml
