regulator: refcount fixes
Fix some refcounting issues in the regulator framework, supporting
regulator_disable() for regulators that were enabled at boot time
via machine constraints:
- Update those regulators' usecounts after enabling, so they
can cleanly be disabled at that level.
- Remove the problematic per-consumer usecount, so there's
only one level of enable/disable.
Buggy consumers could notice different bug symptoms. The main
example would be refcounting bugs; also, any (out-of-tree) users
of the experimental regulator_set_optimum_mode() stuff which
don't call it when they're done using a regulator.
This is a net minor codeshrink.
