When using 'imply IIO' for other configurations which have 'select GPIOLIB'
the following recursive dependency is detected for AD5592R/AD5593R

Switch from 'select GPIOLIB' to 'depends on GPIOLIB' to avoid this per
recommendation in kconfig-language.rst

drivers/gpio/Kconfig:14:error: recursive dependency detected!
drivers/gpio/Kconfig:14:        symbol GPIOLIB is selected by AD5592R
drivers/iio/dac/Kconfig:93:     symbol AD5592R depends on IIO
drivers/iio/Kconfig:6:  symbol IIO is implied by HID_MCP2221
drivers/hid/Kconfig:1227:       symbol HID_MCP2221 depends on GPIOLIB
