Boris BREZILLON f72fa00f8a watchdog: at91sam9_wdt: increase security margin on watchdog counter reset
Try to reset the watchdog counter 4 or 2 times more often than actually
requested, to avoid spurious watchdog reset.
If this is not possible because of the min_heartbeat value, reset it at
the min_heartbeat period.
