[PATCH 4.19 30/61] gpio: fix gpio-adp5588 build errors

[Greg Kroah-Hartman]

[ 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 âadp5588_irq_handlerâ:
../drivers/gpio/gpio-adp5588.c:266:26: error: âstruct gpio_chipâ has no member named âirqâ
            dev->gpio_chip.irq.domain, gpio));
                          ^
../drivers/gpio/gpio-adp5588.c: In function âadp5588_irq_setupâ:
../drivers/gpio/gpio-adp5588.c:298:2: error: implicit declaration of function âgpiochip_irqchip_add_nestedâ [-Werror=implicit-function-declaration]
  ret = gpiochip_irqchip_add_nested(&dev->gpio_chip,
  ^
../drivers/gpio/gpio-adp5588.c:307:2: error: implicit declaration of function âgpiochip_set_nested_irqchipâ [-Werror=implicit-function-declaration]
  gpiochip_set_nested_irqchip(&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.
