[PATCH v12 7/7] pinctrl: qcom: Update clock voting as optional

[Srinivasa Rao Mandadapu]

Update bulk clock voting to optional voting as ADSP bypass platform doesn't
need macro and decodec clocks, as these macro and dcodec GDSC switches are
maintained as power domains and operated from lpass clock drivers.
