The only usage of ar2315_pci_irq_domain_ops is to pass its address to
irq_domain_add_linear() which takes a pointer to const struct
irq_domain_ops. Make it const to allow the compiler to put it in
read-only memory.

"This contains:

- a series of fixes for interrupt drivers to prevent a potential race
when installing a chained interrupt handler

- a fix for cpumask pointer misuse

- a fix for using the wrong interrupt number from struct irq_data

- removal of unused code and outdated comments

- a few new helper functions which allow us to cleanup the interrupt
handling code further in 4.3

I decided against doing the cleanup at the end of this merge window
and rather do the preparatory steps for 4.3, so we can run the final
ABI change at the end of the 4.3 merge window with less risk"
