mb/google/skywalker: Disable CHROMEOS_USE_EC_WATCHDOG_FLAG

Browse source 
Now that we use the WATCHDOG_TOMBSTONE section to store the watchdog
event magic, there is no need to ask EC for the last reset reason. In
fact, with MEDIATEK_WDT_RESET_BY_SW enabled, EC doesn't even record the
watchdog reset reason.

Enable CHROMEOS_USE_EC_WATCHDOG_FLAG only if MEDIATEK_WDT_RESET_BY_SW is
disabled.
