[PATCH v4 19/21] power: regulator: qcom-rpmh-regulator: port ops to U-Boot

Tue Jul 9 11:34:47 CEST 2024
Port over the regulator ops to U-Boot's regulator API. Add back the
pmic5 mode map using U-Boot dm_regulator_mode API and adjust the
pmic5_pldo and pmic5_pldo_lv definitions. No functional changes.
