* Process the remoteproc exceptions
*

* compared to the equivalent processors on the OMAP family, it is notified
* through a software-designed specific interrupt source in the IPC interrupt
* generation register.
*
* This function just invokes the rproc_report_crash to report the exception
* to the remoteproc driver core, to trigger a recovery.
