These patches are intend to improve dw_wdt in the following two aspects: Firstly, the TOP_INIT may be zero at reset on some HW, so the timeout period may be very short, thus we will see immediate system reset after openning the watchdog. Fix this problem by restarting the counter immediately after WDT enabling.
Secondly, the WDT can also be used to reboot the system with the help of recently introduced restart handler. Tested on Marvell BG2Q DMP board.
