[Jia He <justin.he@xxxxxxx>]

To support virtio-* family device, we have 2 choices (virtio mmio, virtio pci)
on arm64 kvm plat. virtio pci needs pci controller which has not been supported
in arm64 Unikraft. This patch series enable the support of virtio mmio.

  plat/drivers/ofw: Introduce fdt_get_last_node_by_compatible
  plat/drivers: Introduce several helpers for virtio ring
  plat/common: Introduce new platform bus
  plat/virtio: Support virtio_cread/cwrite on arm64
  plat/virtio: Add new virtio_mmio device/driver on arm64
