soc: apple: rtkit: Pass the crashlog to the crashed() callback
Client drivers might want a copy of the crashlog to stash into a
devcoredump blob. Since device memory management can be very variable,
the actual devcoredump implementation is left to client drivers. Pass
the raw crashlog buffer to the client callback so it can use it if
desired.
