[PATCH 4/5] ASoC: intel: sst-mfld-platform-pcm: add .delay support

[Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>]

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

Now ALSA SoC supports .delay for component.
This patch uses it, and not update runtime->delay on .pointer
directly / secretly.
