PCI: iproc: Allow override of device tree IRQ mapping function

Browse Source 
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.
