[PATCH v6 3/4] hw/arm/virt: Update SMMU v3 creation to support non PCI/PCIe device connection

[chunming <chunming_li1234@163.com>]

From: chunming <chunming.li@verisilicon.com>

  . Add "smmuv3_sidmap" to set non PCI/PCIe devices SID value
  . Pass non PCI/PCIe devices SID value to SMMU v3 model creation
