watchdog: make imx2_wdt report boot status correctly
Ioctl WDIOC_GETBOOTSTATUS is supposed to return some information
on why the system did (re)boot recently, value WDIOF_CARDRESET
being used to indicate watchdog induced reboot.
Up to now, imx2_wdt did not provide a value here, always returning
zero to indicate normal boot.
Do evaluate the IMX Watchdog Reset Status Register and
produce WDIOF_CARDRESET with WDIOC_GETBOOTSTATUS in case
of a watchdog induced reset.
