Currently when running the samples/watchdog/watchdog-simple.c
application and forcing a kernel crash by doing:
# ./watchdog-simple &
# echo c > /proc/sysrq-trigger
The system does not reboot as expected.
Fix it by calling imx_sc_wdt_set_timeout() to configure the i.MX8QXP
watchdog with a proper timeout.
