that's the wrong way to do it. What we need is to use the transceiver
notifications to notify every time someone calls usb_gadget_vbus_draw()
and pass the mA parameter as argument to the event notification.
Charger driver should 'subscribe' to transceiver notifications and
use the mA argument to reconfigure charging.
