[ Upstream commit 404ec4e4c169fb64da6b2a38b471c13ac0897c76 ] Newer AMD systems can support multiple PCI segments, where each segment contains one or more IOMMU instances. However, an IOMMU instance can only support a single PCI segment. Current code assumes that system contains only one pci segment (segment 0) and creates global data structures such as device table, rlookup table, etc. Introducing per PCI segment data structure, which contains segment specific data structures. This will eventually replace the global data structures. Also update `amd_iommu->pci_seg` variable to point to PCI segment structure instead of PCI segment ID.
