ASoC: codec: tlv320aic32x4: Convert to GPIO descriptors



of_gpio.h is deprecated, update the driver to use GPIO descriptors.
 - Use devm_gpiod_get_optional to get GPIO descriptor, and set consumer
   name.
 - Use gpiod_set_value to configure output value.

While at here, reorder the included headers.

Checking the DTS that use the device, all are using GPIOD_ACTIVE_LOW
polarity for reset-gpios, so all should work as expected with this patch.
