[PATCH] mfd: fix MAX77693 dependency on IRQ_DOMAIN

[Michal Hocko]

The driver needs CONFIG_IRQ_DOMAIN because it uses max77693_irq_thread and
max77693_irq_init.

drivers/mfd/max77693-irq.c: In function âmax77693_irq_threadâ:
drivers/mfd/max77693-irq.c:217: error: implicit declaration of function âirq_find_mappingâ
drivers/mfd/max77693-irq.c: In function âmax77693_irq_initâ:
drivers/mfd/max77693-irq.c:286: error: implicit declaration of function âirq_domain_add_linearâ
