Please follow everything just like opp-microvolt is defined. Create a new field
in the struct dev_pm_opp, initialize it only once when the OPP is created, that
field should be used here instead of parsing the DT here again. There also needs
to be a debug file in debugfs for this new field.
Search for "supply" and "microvolt" in the OPP core, you will see all the places
that need it.
