[PATCH v1] gpio: max77620: Add missing dependency on GPIOLIB_IRQCHIP

[Dmitry Osipenko <digetx@xxxxxxxxx>]

Driver fails to compile in a minimized kernel's configuration because of
the missing dependency on GPIOLIB_IRQCHIP.

 error: ‘struct gpio_chip’ has no member named ‘irq’
   44 |   virq = irq_find_mapping(gpio->gpio_chip.irq.domain, offset);
