'supplied-to or supplied nodes' is specific to "power-supply core and
battery managed devices/drivers" and not platform specific.
Dependent battery drivers interacts/shares power supply events with the
help of 'supplied_to' 'num_supplicants' and external_power_changed(...)
identifiers which are defined and fixed during driver design, it will be
more meaningful to have it internal to drivers instead DT.
