HID: mcp2221: correct undefined references when CONFIG_GPIOLIB isn't defined 

Singular #ifdef IS_REACHABLE(CONFIG_GPIOLIB) weren't covering all the
gpiolib functions that were being referenced.

Update the code regions that are commented out when CONFIG_GPIOLIB isn't
enabled to avoid errors.

Fixes: 960f9df7c6 ("HID: mcp2221: add ADC/DAC support via iio subsystem")
