Added a simple interface for platform to perform crash recovery. When firmware crashes, wil driver can notify the platform which can trigger a crash recovery process. During the process the platform can request a ram dump from the wil driver as well as control when firmware recovery will start. This interface allows the platform to implement a more advanced crash recovery, for example to reset dependent subsystems in proper order, or to provide its own notifications during the recovery process.
