[1/2] PCI: iproc: make of_irq_parse_and_map_pci() configurable

This patch makes the generic code not use the function
of_irq_parse_and_map_pci() always to get the irqs, but to take a
function the actual driver has provided.  This is needed to make this
function work with drivers not using device tree.

This change looks fine to me.
