Benjamin Valentin 18fe16298c cpu/cc2538: add Watchdog implementation
The Watchdog on the CC2538 only supports 4 intervals (2ms, 16ms, 250ms & 1s).
Since the watchdog timer API specifies a `max_time`, the interval equal or
below that time is selected.

E.g. for `max_time=125ms` the 16ms interval would be selected.
This is outside the tolerance of the `tests/periph_wdt` test.
