Peter Zijlstra f25a5ec582 irq_work: Introduce arch_irq_work_has_interrupt() 
commit c5c38ef3d7 upstream.

The nohz full code needs irq work to trigger its own interrupt so that
the subsystem can work even when the tick is stopped.

Lets introduce arch_irq_work_has_interrupt() that archs can override to
tell about their support for this ability.
