regulator: Allow regulator-regulator supplies to be specified by name
When one regulator supplies another allow the relationship to be specified using names rather than struct regulators, in a similar manner to that allowed for consumer supplies. This allows static configuration at compile time, reducing the need for dynamic init code. Also change the references to LINE supply to be system supply since line is sometimes used for actual supplies and therefore potentially confusing.
