[PATCH v2 8/8] hw/arm/virt: Fix devicetree warnings about node names

[Jean-Philippe Brucker]

The devicetree specification requires that nodes use a generic name
where appropriate. Fix the corresponding dt-validate warnings:

  pl061@9030000: $nodename:0: 'pl061@9030000' does not match '^gpio@[0-9a-f]+$'
  From schema: linux/Documentation/devicetree/bindings/gpio/pl061-gpio.yaml
  pl031@9010000: $nodename:0: 'pl031@9010000' does not match 
'^rtc(@.*|-[0-9a-f])*$'
  From schema: linux/Documentation/devicetree/bindings/rtc/arm,pl031.yaml
  pl011@9000000: $nodename:0: 'pl011@9000000' does not match '^serial(@.*)?$'
  From schema: linux/Documentation/devicetree/bindings/serial/pl011.yaml
  intc@8000000: $nodename:0: 'intc@8000000' does not match 
'^interrupt-controller(@[0-9a-f,]+)*$'
  From schema: 
linux/Documentation/devicetree/bindings/interrupt-controller/arm,gic-v3.yaml
  intc@8000000: 'its@8080000' does not match any of the regexes: 
'^(msi-controller|gic-its|interrupt-controller)@[0-9a-f]+$', '^gic-its@', 
'^interrupt-controller@[0-9a-f]+$', 'pinctrl-[0-9]+'
  From schema: 
linux/Documentation/devicetree/bindings/interrupt-controller/arm,gic-v3.yaml
  smmuv3@9050000: $nodename:0: 'smmuv3@9050000' does not match 
'^iommu@[0-9a-f]*'
  From schema: linux/Documentation/devicetree/bindings/iommu/arm,smmu-v3.yaml
