Subject: [PATCH v3 06/13] regulator: s2mps11: Don't store registered regulators
 in state container

Regulators registered by devm_regulator_register() do not have to be
stored in state container because they are never dereferenced later.
The array of regulator_dev can be safely removed from state container.
