[PATCH 1/3] regulator: max77693: Remove unnecessary **rdev from struct max77693_pmic_dev

[Axel Lin <axel.lin@ingics.com>]

Now we are using devm_regulator_register(), so we don't need to allocate *rdev[]
array to store return value of devm_regulator_register. Use a *rdev variable is
enough for checking return status.
