Add platform_data for the driver which allows to specify whether an external reference voltage is used or not. It is not possible to use the return value of regulator_get() for this since the regulator framework is able to return a dummy regulator in case no regulator has been specified. In this case the driver will always get a valid regulator, no matter if it has been specified or not. Also make the regulator non-optional if platform_data states that an external reference voltage should be used.
