ASoC: au1x: name back to pcm_new()/pcm_free()

ASoC: au1x: name back to pcm_new()/pcm_free()

We have been used pcm_new()/pcm_free(), but switched to
pcm_construct()/pcm_destruct() to use extra parameters [1].

pcm_new()/free() had been removed [2], but each drivers are still
using such function naming. Let's name back to pcm_new()/pcm_free()
again.

[1] commit c64bfc906600 ("ASoC: soc-core: add new pcm_construct/pcmdestruct")
[2] commit e9067bb50278 ("ASoC: soc-component: remove snd_pcm_ops from component driver")
