Allocate the memory with scoped/cleanup.h in audio_iio_aux_probe() to
reduce error handling (less error paths) and make the code a bit
simpler.

"io-channel-names" is expected to have few values, so there is no real
point to allocate audio_iio_aux_chan structure with a dedicate memory
allocation.
Using a flexible array for struct audio_iio_aux->chans avoids the
overhead of an additional, managed, memory allocation.
This also saves an indirection when the array is accessed.
Finally, __counted_by() can be used for run-time bounds checking if
configured and supported by the compiler.

Industrial I/O devices can be present in the audio path.
These devices needs to be used as audio components in order to be
fully integrated in the audio path.
This support allows to consider these Industrial I/O devices as
auxiliary audio devices and allows one to control them using mixer
controls.
