From: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>

It is easy to read code if it is cleanly using paired function/naming,
like start <-> stop, register <-> unregister, etc, etc.
But, current ALSA SoC code is very random, unbalance, not paired, etc.
It is easy to create bug at the such code, and is difficult to debug.

This patch adds missing soc_del_dai() and snd_soc_unregister_dai().
