[PATCH v2] ASoC: codec: tlv320adc3xxx: add GPIOLIB dependency

[Randy Dunlap <rdunlap@infradead.org>]

Fix build errors when CONFIG_GPIOLIB is not enabled:

../sound/soc/codecs/tlv320adc3xxx.c: In function 'adc3xxx_i2c_probe':
../sound/soc/codecs/tlv320adc3xxx.c:1352:28: error: implicit declaration of function 'devm_gpiod_get'; did you mean 'devm_gpio_free'? [-Werror=implicit-function-declaration]
 1352 |         adc3xxx->rst_pin = devm_gpiod_get(dev, "reset", GPIOD_OUT_LOW);
../sound/soc/codecs/tlv320adc3xxx.c:1352:57: error: 'GPIOD_OUT_LOW' undeclared (first use in this function); did you mean 'GPIOF_INIT_LOW'?
 1352 |         adc3xxx->rst_pin = devm_gpiod_get(dev, "reset", GPIOD_OUT_LOW);
  CC      lib/dynamic_debug.o
../sound/soc/codecs/tlv320adc3xxx.c:1400:9: error: implicit declaration of function 'gpiod_set_value_cansleep'; did you mean 'gpio_set_value_cansleep'? [-Werror=implicit-function-declaration]
 1400 |         gpiod_set_value_cansleep(adc3xxx->rst_pin, 1);
