Document the watchdog timeout mode property. If this property is used
the user can select what happens on watchdog timeout. Set this property
to 1 to enable SHUTDOWN (the device resets), set it to 0 and the device
will go to POWERDOWN on watchdog timeout.

Only use this option if you can't use the watchdog automatic suspend
function during a suspend (see register CONTROL_B).

Why does it need a value ? Why not just bool ?
