soc: qcom: watchdog_v2: Add support to trigger watchdog bite on panic 



In certain cases during a kernel panic, interrupts on non-panicking
CPUs are disabled. Since CPU context cannot be collected by sending IPIs
to those CPUs, it impacts debugging the problem. Forcing a watchdog bite
during kernel panic will ensure us getting the proper CPU context. Hence
adding support for the same.
