From: Arnd Bergmann <arnd@arndb.de>

The ad4062 driver gained support for the gpiochip and now fails
to build when GPIOLIB is disabled:

390-linux-ld: drivers/iio/adc/ad4062.o: in function `ad4062_gpio_get':
drivers/iio/adc/ad4062.c:1383:(.text+0x3dc): undefined reference to `gpiochip_get_data`

Add a Kconfig dependency for this.

Fixes: da1d3596b1e4 ("iio: adc: ad4062: Add GPIO Controller support")
