There are a couple of these operations that are good candidates to be
shared between all Qualcomm remoteproc drivers. I just haven't spent the
time to figure out how to properly splice it.

For the crash reason specifically, there are three operations done in
the other drivers; read-and-null-terminate, then this is outputed to the
log, also indicating what type of event we had. And finally the
remoteproc core is informed about the crash, with a event-type passed
and we get another line in the log based on that, i.e. there's room for
a few improvements in this area.
