But the usb-phy framework is not used on all boards/platforms. At support for registering the Vbus boost converter as a standard regulator when there is no usb-phy on the board. Also add support for providing regulator_init_data through platform_data for use on boards where device-tree is not used and the platform code must thus provide the regulator_init_data.
