We cannot unlock the watchdog timer within 3 watch dog ticks of touching
it per the datasheet. This is actually around 100ms so we should protect
against this.
Note: To avoid bringing in other dependencies into the npcx_monitor_fw,
the "old" method of stopping the watchdog is used (no waiting first).

Without this include, the `watchdog_reload()` function will be compiled
as a noop unless "config.h" is included before "watchdog.h" in whatever
compilation unit requires watchdog functionality.

Increase watchdog timeout to 1.8 second. The pd_task can delay up
to 1.5 seconds, so the watchdog must be at least that value.
On Zinger, the new timeout period will be 2 seconds with LSI clock at 50kHz
and 3.36 seconds with LSI clock at 30kHz.
Note: the LSI frequency range is tighter on STM32F0 and cannot go up to
56kHz.
BUG=none
BRANCH=none
TEST=add 1.5 second blocking delay to pd_task and make sure
watchdog is normally not firing.

Watchdog module added. Off by default because of following limitations:
- When programming, the WD fires, and programming fails. For now, you
have to program twice.

Currently, we need to have #ifdefs everywhere watchdog_reload() is
called. With this fix we don't.
Also don't bother including unused hardware timer watchdog code if the
watchdog isn't defined.
No change when CONFIG_WATCHDOG is defined (which it is for all normal builds).

We want this function to be available for all chips, so move it into a
generic place.
The task_disable_irq() from the LM4 version can be left in
watchdog_check(), to keep the watchdog_trace() function generic.

Use the same prototype for watchdog_init() everywhere. One version takes
a parameters and one doesn't. We don't need the parameter since we have
a #define. Tidy this up.
Also move watchdog defines into watchdog.h.

Preparatory work to introduce a second SoC : 2nd series 1/4
The atomic operations are SoC independant since they are only using
LDREX/STREX instructions which are just core specific ARMv7-M).
