powermgmt: Small cleanups to battery capacity code

- Don't include the 'battery capacity' setting unless the
  target allows changing it.
- Clean up the preprocessor conditionals used to check for
  variable battery capacity support.
- Don't use a variable for battery capacity unless it is
  actually needed.
