[PATCH v2 2/8] hw/arm/virt: Fix devicetree warning about the GIC node

[Jean-Philippe Brucker]

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
