ASoC: Intel: sof_sdw: add controls and dapm widgets in codec_info

Currently, we add card controls and dapm widgets one by one in the
codec_info->dais->rtd_init callback. Duplicated controls and dapm
widgets will be added if there are more than one types of amps in the
dai link. Moving it to sof_sdw_rtd_init() and only add the
controls/widgets of the first codec dai can avoid the duplications.
