iio: adc: bd79124: Add GPIOLIB dependency

Browse Source 
The bd79124 has ADC inputs which can be muxed to be GPIOs. The driver
supports this by registering a GPIO-chip for channels which aren't used
as ADC.

The Kconfig entry does not handle the dependency to GPIOLIB, which
causes errors:

ERROR: modpost: "devm_gpiochip_add_data_with_key" [drivers/iio/adc/rohm-bd79124.ko] undefined!
ERROR: modpost: "gpiochip_get_data" [drivers/iio/adc/rohm-bd79124.ko] undefined!

at linking phase if GPIOLIB is not configured to be used.

Fix this by adding dependency to the GPIOLIB.
