USB: OTG: Notify the charger type to the PMIC driver
Till now, we are communicating only the amount of the current that
should be drawn by the PMIC for charging from the OTG driver through
power supply class driver. With this change, we notify the type of the
charger connected as well, so that userspace can benefit for dispalying
the charger type in the UI.
