With the commit4fcba5d556("regulator: implement basic reference counter"), keeping regulator enablement in balance become more important. Calling regulator_autoset multiple times on a fixed regulator increase the enable count for each call, resulting in an unbalanced enable count. Introduce a AUTOSET_DONE flag and use it to mark that autoset has run for the regulator. Return -EALREADY on any subsequent call to autoset. This fixes so that the enable count is only ever increased by one per regulator for autoset.
