This check required for distingushing ADSP based platforms and ADSP bypass platforms. In case of ADSP enabled platforms, where audio is routed through ADSP macro and decodec GDSC Switches are triggered as clocks by pinctrl driver and ADSP firmware controls them. So It's mandatory to enable them in ADSP based solutions. In case of ADSP bypass platforms clock voting is optional as these macro and dcodec GDSC switches are maintained as power domains and operated from lpass clock drivers.
