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.
