ipmi-watchdog: Make it possible to set DONT_STOP

The IPMI standard supports setting a DONT_STOP bit during an Watchdog
Set operation. Most of the time we don't want to stop the Watchdog when
updating the settings so we should be using this bit. This patch makes
it possible for callers of set_wdt to prevent the watchdog from being
stopped. This only changes the behavior of the watchdog during the
initial settings update when initializing skiboot. The watchdog is no
longer disabled and then immediately re-enabled.
