Add arm64 support to the iProc PCIe driver. Note that on arm32, bus->sysdata points to the arm32-specific pci_sys_data struct, and pci_sys_data.private_data contains the iproc_pcie pointer. For arm64, there's nothing corresponding to pci_sys_data, so we keep the iproc_pcie pointer directly in bus->sysdata. In addition, arm64 does IRQ mapping in pcibios_add_device(), so it doesn't need pci_fixup_irqs() as arm32 does.
