ASoC: mediatek: 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, 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.

ASoC: mediatek: remove snd_pcm_ops

snd_pcm_ops is no longer needed.
Let's use component driver callback.

ASoC: mediatek: add sub dai to mtk_base_afe

In MediaTek SoC chip we have multiple DAI,
such as I2S, ADDA, PCM, etc.

Organize each DAI in to one sub dai,
with its dai driver, controls, widgets, routes.

add mtk_afe_combine_sub_dai() to combine
dai driver from each DAI.

add mtk_afe_add_sub_dai_control() to register
the control, widget, routes to component.
