Subject: [PATCH v2 04/12] irqchip/irq-bcm7038-l1: Use irq_get_irq_data()

Using irq_desc_get_irq_data(irq_to_desc()) to retrieve the irq_data
structure from a virtual interrupt number is going to be problematic to
make irq-bcm7038-l1 a module because irq_to_desc() is not exported, and
there is no intent to export it to modules, see 64a1b95bb9fe ("genirq:
Restrict export of irq_to_desc()").
