power: regulator: Only run autoset once for each regulator
With the commit 4fcba5d556b4 ("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.
