ASoC: Intel: fix sof-nau8825 link failure

The snd-soc-sof_nau8825.ko module fails to link unless the
sof_realtek_common support is also enabled:

ERROR: modpost: "sof_rt1015p_codec_conf" [sound/soc/intel/boards/snd-soc-sof_nau8825.ko] undefined!
ERROR: modpost: "sof_rt1015p_dai_link" [sound/soc/intel/boards/snd-soc-sof_nau8825.ko] undefined!
