What is "core regulator" to the regulator chip itself?

No, the driver should be able to figure out for itself what regulators
are on the chip purely by knowing what chip it's talking to.  If there
is some configuration on the board from selection of passives or similar
the platform data should reflect how that's done (eg, supply the
relevant values for the passives).
