PCI: iproc: Add arm64 support
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.
