Subject: [PATCH 02/11] genirq: Export irq_to_desc() again to modules

In order to build drivers/irqchip/irq-bcm7038-l1.c as a module (for use
in GKI), we need to export_to_desc() which is used in this snippet of
code:

	irqd_set_single_target(irq_desc_get_irq_data(irq_to_desc(virq)));

This effectively reverts 64a1b95bb9fe ("genirq: Restrict export of
irq_to_desc()").
