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.
acp3x-pcm-dma driver is using snd_soc_rtdcom_lookup() at
open/close() to get component by using DRV_NAME.
But, lookuped "component" and function parameter "component"
are same. We don't need to use snd_soc_rtdcom_lookup().
This patch fixup it.
