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.

The DFSDM can support a larger rate range than currently
supported in driver.
Increase rate upper limit to 48kHz and allow all rates
in the range 8kHz to 48kHz.

Modify snd_soc_add_component so it calls snd_soc_component_initialize
no longer and thus providing true two-step registration. Drivers may
choose to change component's fields before actually adding it to ASoC
subsystem.

ASoC: Fixes for v5.5
This is mostly driver specific fixes, plus an error handling fix
in the core. There is a rather large diffstat for the stm32 SAI
driver, this is a very large but mostly mechanical update which
wraps every register access in the driver to allow a fix to the
locking which avoids circular locks, the active change is much
smaller and more reasonably sized.

In stm32_afsdm_pcm_cb function, the transfer size is provided in bytes.
However, samples are copied as 16 bits words from iio buffer.
Divide by two the transfer size, to copy the right number of samples.

Clean up the drivers with the new managed buffer allocation API.
The superfluous snd_pcm_lib_malloc_pages() and
snd_pcm_lib_free_pages() calls are dropped, as well as the superfluous
snd_pcm_lib_preallocate_free_for_all() call. As of the result,
hw_free and pcm_destruct ops became empty and got removed.

snd_pcm_lib_preallocate_pages() and co always succeed, so the error
