Update bulk clock voting to optional voting as ADSP bypass platform doesn'tSorry for missing your reply on my question on the previous version, I
need macro and decodec clocks, as these macro and dcodec GDSC switches are
maintained as power domains and operated from lpass clock drivers.
think this sounds reasonable.
Okay will change accordingly.
