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.
intel baytrail driver is using it, but we can avoid it easily by having component pointer at sst_byt_pcm_data. This patch removes snd_soc_rtdcom_lookup() from this driver.
