Harald Welte 81c9e06f63 WIP: design for a multi-voltage USB UART 
* an adjustible LDO with rotary switch is able to configure the UART
  voltage levels as needed.
* alternatively, the UART logic level voltage (in the 1.8-3.3V range)
  can be provided by an external voltage reference.
* TVS diodes protect the USB and UART sides from overvoltage and ESD
* all voltages are available on a header to supply external circuitry
* five GPIO pins are available on a header
