[PATCH] irq: export handle_simple_irq, irq_modify_status, irq_to_desc, irq_alloc_descs and irq_free_descs

V2: add irq_alloc_descs and irq_free_descs for dynamic pool allocation.

This is to allow their use in IIO. We have complete control of
both the irq_chip creation and requesting of irqs so would like
to be able to build as a module. That requires these exports.
