[RESEND PATCH 1/2] genirq: export irq_can_set_affinity() for module drivers

[Hangtian Zhu]

Export irq_can_set_affinity() for loadable drivers that need a runtime
check for IRQ affinity capability.

In hierarchical IRQ setups where the effective irqchip path lacks
.irq_set_affinity(), drivers may need to switch to a fallback policy.
Without this export, module drivers cannot use the core helper and have
to open-code equivalent checks.
