Subject: [PATCH] ALSA: hda: cirrus_scodec: Select GPIOLIB for KUnit test

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'
