[PATCH v6 7/7] pinctrl: qcom: Update clock voting as optional

[Srinivasa Rao Mandadapu <quic_srivasam@quicinc.com>]

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