boards/sodaq-sff: add support for SODAQ SFF
The following features were tested (briefly): * UART (the first, and the second connected to the UBlox SARA) * xtimer * I2C (using driver BMX280 and SHT2x) * ADC * WDT * RGB-LEDs SPI isn't tested, but it should be working.

|

|

* ### General information
|
||||
*
|
||||
* General information about this board can be found on the
|
||||
* [SODAQ support](https://support.sodaq.com/Boards/Sara_SFF/)
|
||||
* website.
|
||||
* Schematic can be found [here](https://learn.sodaq.com/Boards/Sara_SFF/sodaq_sara_sff_r2.pdf)
|
||||
)
|
||||
*
|
||||
* ### Flash the board
|
||||
*
|
||||
* Use `BOARD=sodaq-one` with the `make` command.<br/>
|
||||
* Example with `hello-world` application:
|
||||
* ```
|
||||
* make BOARD=sodaq-one -C examples/hello-world flash
|
||||
* ```
|
||||
*
|
||||
* @note If the application crashes, automatic reflashing via USB, as explained
|
||||
* above won't be possible. In this case, the board must be set in
|
||||
* bootloader mode by double tapping the reset button before running the
|
||||
* flash command.
|
||||
*
|
||||
* ### Accessing STDIO via UART
|
||||
*
|
||||
* STDIO of RIOT is directly available over the USB port.
