This patch adds a binding to guide the remoteproc core on how to deal with remote processors in two cases: 1) When an application holding a reference to a remote processor character device interface crashes. 2) when the platform driver for a remote processor is removed. In both cases if "autonomous-on-core-reboot" is specified in the remote processor DT node, the remoteproc core will detach the remote processor rather than switching it off.
