[RFT PATCH v2 25/42] PCI: Add IRQ mapping function pointers to pci_host_bridge struct

[Lorenzo Pieralisi]

From: Matthew Minter <matt at masarand.com>

In order to defer IRQ assignment arches must be able to register functions
to map and swizzle interrupts. These registered functions are stored in
the pci_host_bridge struct.
