Prior to commit efb0cb50c427 ("regulator: qcom-rpmh: Implement get_optimum_mode(), not set_load()") the above meant that we were able to set either LPM or HPM mode. After that commit (and fixes [1]) we'll be stuck at the initial mode. Discussion of this has resulted in the decision that the old dts files were wrong and should be fixed to fully restore old functionality. Let's re-enable the old functionality by fixing the dts.
