Some chargers can run in a "turbo" mode, which lets it draw from the battery
to provide extra power to the AP in short bursts. In order for this to work
properly, the EC has to watch the current closely to make sure specific
limits are observed. It also has to recognize specific adapters, since those
limits vary depending on the rated power that the adapter can provide.
This adds the basic functionality, plus a test for it.
