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.
