PCI: iproc: Add inbound DMA mapping support
Add support for inbound DMA mapping. The range of the inbound mapping is
configured by the optional device tree property 'dma-ranges'.
While inbound mapping is done automatically in the ASIC on most iProc-based
SoCs, newer ASICs (e.g., Stingray) require inbound mapping to be configured
explicitly in software.

and uninitialized return value in iproc_pcie_setup_ib() from Arnd Bergmann
