ASoC: stm32: dfsdm: add stm32_adfsdm_dummy_cb() callback

Adapt STM32 DFSDM driver to a change in iio_channel_get_all_cb() API.
The callback pointer becomes a requested parameter of this API,
so add a dummy callback to be given as parameter of this function.
However, the stm32_dfsdm_get_buff_cb() API is still used instead,
to optimize DMA transfers.
