ASoC: codec: tpa6130a2: 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 with default
  polarity GPIOD_OUT_LOW, set consumer name.
- Use gpiod_set_value to configure output value.

Checking the DTS polarity, all users are using GPIOD_ACTIVE_HIGH.
so all should work as expected with this patch.
