mfd: ab8500: Fix dt irq mapping
The AD8500 defines itself as interrupt-controller in DT, but it doesn't assign DT node to IRQ domain when creates it. As result, of_irq_xx() helpers don't work because they can't find necessary IRQ domain. Hence, fix it by assigning AD8500 core device DT node to IRQ domain when it's created.
