Subject: [PATCH] ASoC: cs53l30: include gpio/consumer.h

When GPIOLIB is disabled, we don't see the declarations from
gpio/consumer.h, so we have to include the header explicitly
to avoid this build error:

sound/soc/codecs/cs53l30.c: In function 'cs53l30_i2c_probe':
sound/soc/codecs/cs53l30.c:931:24: error: implicit declaration of function 'devm_gpiod_get_optional' [-Werror=implicit-function-declaration]
  cs53l30->reset_gpio = devm_gpiod_get_optional(dev, reset,
                        ^~~~~~~~~~~~~~~~~~~~~~~
sound/soc/codecs/cs53l30.c:932:13: error: 'GPIOD_OUT_LOW' undeclared (first use in this function)
             GPIOD_OUT_LOW);
             ^~~~~~~~~~~~~
sound/soc/codecs/cs53l30.c:932:13: note: each undeclared identifier is reported only once for each function it appears in
sound/soc/codecs/cs53l30.c:939:3: error: implicit declaration of function 'gpiod_set_value_cansleep' [-Werror=implicit-function-declaration]
   gpiod_set_value_cansleep(cs53l30->reset_gpio, 1);
