[PATCH v6 2/4] hw/arm/smmuv3: Update CFGI commands to support non PCI/PC


From: chunming
Subject: [PATCH v6 2/4] hw/arm/smmuv3: Update CFGI commands to support non PCI/PCIe devices
Date: Thu, 2 Sep 2021 16:14:27 +0800

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

  "smmu_iommu_mr" function can't get MR according to SID for non PCI/PCIe 
devices.
  Look up in the platform device list: peri_sdev_list for non PCI/PCIe devices.
