gpio: fix gpio-adp5588 build errors

BugLink: https://bugs.launchpad.net/bugs/1838824
[ Upstream commit e9646f0f5bb62b7d43f0968f39d536cfe7123b53 ]

The gpio-adp5588 driver uses interfaces that are provided by
GPIOLIB_IRQCHIP, so select that symbol in its Kconfig entry.

Fixes these build errors:

../drivers/gpio/gpio-adp5588.c: In function ‘adp5588_irq_handler’:
../drivers/gpio/gpio-adp5588.c:266:26: error: ‘struct gpio_chip’ has no member named ‘irq’
            dev->gpio_chip.irq.domain, gpio));
                          ^
../drivers/gpio/gpio-adp5588.c: In function ‘adp5588_irq_setup’:
../drivers/gpio/gpio-adp5588.c:298:2: error: implicit declaration of function ‘gpiochip_irqchip_add_nested’ [-Werror=implicit-function-declaration]
  ret = gpiochip_irqchip_add_nested(&dev->gpio_chip,

          Say yes here to enable the adp5588 to be used as an interrupt
          controller. It requires the driver to be built in the kernel.
