No, don't do this - introducing special snowflake bindings just makes
things more complex at the system level and tells everyone else that
they too can have special snowflake bindings. Someone should be able to
connect up the regulators based purely on a schematic. Just describe
the hardware, it's just one extra line in the DT per regulator.
