PCI: xilinx-nwl: Move to struct pci_host_bridge IRQ mapping functions 



struct pci_host_bridge gained hooks to map/swizzle IRQs, so that the IRQ
mapping can be done automatically by PCI core code through the
pci_assign_irq() function instead of resorting to arch-specific
implementation callbacks to carry out the same task which force PCI host
bridge drivers implementation to implement per-arch kludges to carry out a
task that is inherently architecture agnostic.

Add map/swizzle IRQs hooks to the xilinx-nwl PCI host driver to move the
IRQ allocation into core code and stop relying on arch-specific callbacks.
