regulator: provide regulator_bulk_set_supply_names() 



There are many regulator consumers who - before using the regulator
bulk functions - set the supply names in regulator_bulk_data using
a for loop.

Let's provide a simple helper in the consumer API that allows users
to do the same with a single function call.
