regmap-irq: make it possible to add irq_chip do a specific device node
Add a new function regmap_add_irq_chip_np() with its corresponding devm_regmap_add_irq_chip_np() variant. Sometimes one want to register the IRQ domain on a different device node that the one of the regmap node. For example when using a MFD where there are different interrupt controllers and particularly for the generic regmap gpio_chip/irq_chip driver. In this case it is not desireable to have the IRQ domain on the parent node.
