It enables USB-related DT nodes (controller and PHY) and modifies the charger driver (BQ256XX) to expose its VBUS state through extcon. Driver change is required since the device has its VBUS connected to the charger IC, which means cable connection/disconnection events must be fed from the charger IC, to the controller driver to dynamically enable/disable the USB gadget functionality.
