Currently many IRQ mapping functions and data structures use the __init and __initdata optimisations. These result in the relevant functions being innaccessible after boot time. However for deferred IRQ assignment it is important to have access to these functions at PCI device enable time. Therefore, remove the optimisation from the relevant data structures and functions to prepare for deferred IRQ assignment.
