The KUnit test for cirrus_scodec uses GPIO library functions so select GPIOLIB in Kconfig.
This fixes the ld failures on builds that didn't already select GPIOLIB. ld: vmlinux.o: in function `cirrus_scodec_test_gpio_get': sound/pci/hda/cirrus_scodec_test.c:40: undefined reference to `gpiochip_get_data' ld: vmlinux.o: in function `cirrus_scodec_test_gpio_probe': sound/pci/hda/cirrus_scodec_test.c:94: undefined reference to `gpiochip_generic_request' ld: sound/pci/hda/cirrus_scodec_test.c:94: undefined reference to `gpiochip_generic_free' ld: sound/pci/hda/cirrus_scodec_test.c:95: undefined reference to `devm_gpiochip_add_data_with_key'
