MFC r356649: regulator: small enhancements to regulator_shutdown

Highlights:

- Exit early if we're not disabling unused regulators; there's no need to
  take the regulator topology lock and re-evaluate this every iteration, as
  it's not going to change.
- Don't emit a notice that we're shutting down a regulator if it's not
  enabled, to reduce noise.
- Mention the outcome of the shutdown, to aide debugging and easily let
  developer/user collect list of regulators we actually shutdown to
  determine problematic one.
