                When using EXT1 wakeup source without external pull-up/downs, you may want to make use of
                the internal ones.

                if we turn off the RTC_PERIPH domain or if certain chips lack the RTC_PERIPH domain,
                we will use the HOLD feature to maintain the pull-up and pull-down on the pins during sleep.
                but if we turn on the RTC_PERIPH domain, we don not need to use HOLD feature and this will
                increase some power comsumption.

                EXT0 wakeup source resides in the same power domain as RTCIO (RTC Periph), so internal
                pull-up/downs are always available. There's no need to explicitly force it on for EXT0.
