remoteproc: omap: trigger recovery for device exceptions
The omap remoteproc driver detects device exceptions when a mailbox
crash message is sent by the remote core.
The omap remoteproc driver notifies the remoteproc core using the
rproc_error_reporter function to trigger a recovery in the event
of any device exceptions.
