genirq: Introduce generic irq migration for cpu hotunplug
ARM and ARM64 have almost identical code for migrating interrupts on
cpu hotunplug. Provide a generic version which can be used by both.
The new code addresses a shortcoming in the ARM[64] variants which
fails to update the affinity change in some cases. The solution for
this is to use the core function irq_do_set_affinity() instead of open
coding it.
[ tglx: Added copyright notice and license boilerplate. Rewrote
subject and changelog. ]
