Bug description:
  Three patches are needed to add support for Amazon / Annapurna Labs
  "Graviton" PCIe controller, which is required for future AWS instance
  types.

  The feature is to be enabled for Ubuntu kernels >= linux-aws-bionic.

  The first patch is from mainline; the other two are AWS specific
  quirks from Amazon Linux, not yet upstream.

  UBUNTU: SAUCE: [aws] irqchip/gic-v2m: invoke from gic-v3 initialization and 
add acpi quirk flow
  UBUNTU: SAUCE: [aws] arm64: acpi/pci: invoke _DSM whether to preserve 
firmware PCI setup
