[PATCH] gpio: regmap: disable IRQ domain without GPIOLIB_IRQCHIP

[Álvaro Fernández Rojas <noltari@xxxxxxxxx>]

The current code doesn't check if GPIOLIB_IRQCHIP is enabled, which results in
a compilation error when trying to build gpio-regmap without having selected
CONFIG_GPIOLIB_IRQCHIP.

Fixes: ebe363197e52 ("gpio: add a reusable generic gpio_chip using regmap")
