gpio: guard gpiochip_irqchip_add_domain() with GPIOLIB_IRQCHIP
[ Upstream commit 9c7d24693d864f90b27aad5d15fbfe226c02898b ]
The current code doesn't check if GPIOLIB_IRQCHIP is enabled, which results in
a compilation error when trying to build gpio-regmap if CONFIG_GPIOLIB_IRQCHIP
isn't enabled.
Fixes: 6a45b0e2589f ("gpiolib: Introduce gpiochip_irqchip_add_domain()")
