Subject: [PATCH v2 1/3] pinctrl: qcom: Update lpass variant independent functions as generic

Update pin control variable names to make common for all lpass varients.
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.
