msi-map properties are used to tell an OS how PCI requester IDs are mapped to ARM SMMU stream IDs. for all PCI devices discovered in a system: -allocate a LUT (look-up-table) entry in that PCI controller -allocate a stream ID for the device -program and enable a LUT entry (maps PCI requester id to stream ID) -set the msi-map property on the controller reflecting the LUT mapping basic bus scanning loop/logic was taken from drivers/pci/pci.c pci_hose_scan_bus().
