Add watchdog0 to support tests/drivers/watchdog/wdt_basic_api. Solve tests code runtime error on it8xxx2_evb: 1.When run the wdt tests api, we shouldn't reduce the warning timer time, so I add config WDT_ITE_REDUCE_WARNING_LEADING_TIME, this config will be enabled only on platform EC. 2.Upper limit window timeouts can't be 0 when we install timeout. 3.Since we support wdt_it8xxx2_disable(), then we should support flag WDT_OPT_PAUSE_HALTED_BY_DBG, too. Watchdog can be stopped by IT8XXX2_WDT_EWDSCEN bit of ETWCTRL reg. Signed-off-by: Ruibin Chang <Ruibin.Chang@ite.com.tw>

Once warning timer triggered, if watchdog timer isn't reloaded,
|
|
then we will reduce interval of warning timer to 30ms to print
|
|
more warning messages before watchdog reset.
