When using 'imply IIO' for other configurations which have 'select GPIOLIB'
the following recursive dependency is detected for STX1040

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 STX104
drivers/iio/addac/Kconfig:20:   symbol STX104 depends on IIO
drivers/iio/Kconfig:6:  symbol IIO is implied by HID_MCP2221
drivers/hid/Kconfig:1227:       symbol HID_MCP2221 depends on GPIOLIB

Given this wants to go in with the patch that causes the problem (and definitely
not after it!)- I'll assume this will go via the HID tree.
