msm: msm_watchdog_v2: Increase watchdog bark timeout during panic 



We now wait for 10 seconds during panic handling before triggerring a
watchdog bark. This is done because the earlier timeout of 4 seconds
was not sufficient for all targets which resulted in the device resetting
in the middle of the panic handler.
