watchdog:rit_wdt: Add support for WDIOF_CARDRESET
This patch adds the WDIOF_CARDRESET support for the platform watchdog
whose hardware does not support this feature, to know if the board
reboot is due to a watchdog reset.
This is done via reserved memory(RAM), which indicates if specific
info saved, triggering the watchdog reset in last boot.
