[PATCH] genirq: irq: remove msi hacks

Browse source 
Because of the nasty way that CONFIG_PCI_MSI was implemented we wound up with
set_irq_info and set_native_irq_info, with move_irq and move_native_irq.  Both
functions did the same thing but they were built and called under different
circumstances.  Now that the msi hacks are gone we can kill move_irq and
set_irq_info.
