soc: qcom: watchdog_v2: Add support to trigger watchdog bite on panic
In certain cases during a kernel panic,the interrupts on non-panicking
CPUs are disabled. Since CPU context cannot be collected by sending IPI
to those CPUs, we're limited to debug the problem. Forcing a watchdog
bite during kernel panic will ensure us getting the proper CPU context.
Hence adding support for the same.
