So far we have been doing all proxy votes by voting for raw voltages/load through the regulator interface. But actually VDDCX and VDDMX represent power domains that should be preferably managed using corner votes through the power domain interface. Document that those should be specified as power domains for qcom,pronto-v1/2-pil and deprecate using them through the regulator interface.
