Vincent Palatin f771cca719 stm32l: add watchdog support ...

Use the Independant WatchDog.
The Window WatchDog would provide a nice early warning interrupt before
actually rebooting but the max period (128 ms) is probably too short for
our purpose.

The full GPIO support and the reboot cause detection will be implemented
in later steps.

Signed-off-by: Vincent Palatin <vpalatin@chromium.org>

BUG=None
TEST=on Discovery board, do blocking waits of 500ms and 1500ms, and
check the latter reboots the platform and the former does not.
