The board shall be able to detect when a charge cable that is plugged in is wired to a charger.

The USB documentation notes that in this case, D+ & D- will be tied togethers, and a 1.5A current will be available.
We must check if this is true on proprietary chargeurs.

The state of CC1 CC2 pins can also give a clue.

The CC part was done in #24.
The detection of legacy USB A charger (BC1 protocol) is maybe not possible with the current hardware.

This issue should be left open until BC1 is supported.
