sh/PCI: Remove __init optimisations from IRQ mapping functions/data

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.

PCI: Make the struct pci_dev * argument of pci_fixup_irqs const.

Aside of the usual motivation for constification, this function has a
history of being abused a hook for interrupt and other fixups so I turned
this function const ages ago in the MIPS code but it should be done
treewide.

Due to function pointer passing in varous places a few other functions
had to be constified as well.

This consolidates the PCI initialization code for all of the pci-sh7780
