The approach taken here is to introduce 2 new separate drivers: one for the eusb2 and one for the usbcon. The eusb2 driver is modelled to take a phandle to the usbcon and configure/unconfigure it for the eUSB2 to become accessible and not cause a hang whenever its registers are touched. A new USBDP driver will be added later on, so that pipe3 and super-speed can be configured.
