Certain SoCs require the PCIe outbound mapping to be configured in
software. Add support for those chips.
[jonmason: Use %pap format when printing size_t to avoid warnings in 32-bit
build.]
[arnd: Use div64_u64() instead of "%" to avoid __aeabi_uldivmod link error
in 32-bit build.]

The resource list is only used in the setup process and was never freed.
pci_add_resource() allocates a memory area to store the list item.
Fix the memory leak.

The struct iproc_pcie.resources member was pointing to a stack variable and
is invalid after the registration function returned.
Remove this pointer and add a parameter to the 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.

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.
