ASoC: intel: skylake: Use managed buffer allocation
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.
The pcm_construct ops contains only the superfluous call of
snd_pcm_lib_preallocate_free_for_all(), so dropped, too.
