[PATCH 1/4] ASoC: mediatek: don't use snd_soc_rtdcom_lookup()

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

We shouldn't use snd_soc_rtdcom_lookup() as much as possible.
It works today, but, will not work in the future if we support multi
CPU/Codec/Platform, because 1 rtd might have multiple same driver
named component.

mediatek drivers are using snd_soc_rtdcom_lookup() at
afe->memif_fs and/or afe->irq_fs to get component.
But, caller knows it via dai->component.
We don't need to use snd_soc_rtdcom_lookup().
This patch fixup it.
