soc: qcom: ssr: add crash status to know why subsys crashed
In some specific cases, clients may want to know why subsystem
crashed, for example, in case of watch dog bite, subsystem may not
be able to execute error handling. Which would need different code
paths to be exercised on the apps processor.
