iio: tcs3472: use devm for resource management

Browse source

Convert the driver to use device-managed resource allocation:
- Add tcs3472_powerdown_action() and register it with
  devm_add_action_or_reset() to ensure the device is powered down on
  cleanup.
- Replace iio_triggered_buffer_setup() with
  devm_iio_triggered_buffer_setup().
- Replace request_threaded_irq() with devm_request_threaded_irq().
- Replace iio_device_register() with devm_iio_device_register().
- Replace mutex_init() with devm_mutex_init().
- Remove tcs3472_remove() as all cleanup is now handled by devm.

Use a local 'dev = &client->dev' in tcs3472_probe() to keep the devm
calls compact.
