ASoC: soc-core: add new pcm_construct/pcm_destruct
Current snd_soc_component_driver has pcm_new/pcm_free, but, it doesn't have "component" at parameter. Thus, each callback can't know it is called for which component. Each callback currently is getting "component" by using snd_soc_rtdcom_lookup() with driver name. 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 name component. To solve this issue, each callback need to be called with component. This patch adds new pcm_construct/pcm_destruct with "component" parameter.
