If there is any input supply for reglator then the name of supply need to provided by init_data->supply_regulator. In dt case, the input supply is searched by the <name>-supply and here it is require to fix the name so that correct device node can be identified at the time of regulator registration. Fixing the name for input supply as "regulator-supply".
