PCI: iproc: Add Broadcom iProc PCIe support Add support for the Broadcom iProc PCIe controller. pcie-iproc.c is the common core driver, and a front-end bus interface needs to be added to support different bus interfaces. pcie-iproc-platform.c contains the support for the platform bus interface.

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.

PCI: iproc: Allow override of device tree IRQ mapping function The iProc core PCIe driver defaults to using of_irq_parse_and_map_pci() for IRQ mapping. Add iproc_pcie.map_irq so bus interfaces that don't use device tree can override this by supplying their own IRQ mapping function.
