Fix usb debug dongle support

- move enable_usbdebug() declaration to usbdebug.h
    - reinitialize debug driver in ramstage, as copying the data
      structure from romstage doesn't work right now. This way of copying
      data from romstage to ramstage is really board/cpu specific, and is
      likely to break often. So don't do it.
