Update bulk clock voting to optional voting as ADSP bypass platform doesn't need macro and decodec clocks,
Even I am not sure what "ADSP bypass platform" means, so please express this better.
Are they optional because sc7280 typically come with ADSP based audio, but it might not and if not then we shouldn't control those clocks?
these are maintained as power domains and operated from lpass audio core cc.
So there are clocks, but they are exposed as power-domains? Or are you just trying to say that the LPASS LPI pinctrl block is always in a power-domain controlled by the audio clock-controller?
