From: Xiang Chen <[email protected]> It always calls the IOMMU MR translate() callback with flag=IOMMU_NONE in memory_region_iommu_replay(). Currently, smmuv3_translate() return an IOMMUTLBEntry with perm set to IOMMU_NONE even if the translation success, whereas it is expected to return the actual permission set in the table entry. So pass the actual perm to returned IOMMUTLBEntry in the table entry.
