[PATCH 1/3] remoteproc: xlnx: enable boot recovery

[Tanmay Shah <tanmay.shah@amd.com>]

This is the default method to recover the remote processor from crash.
During this recovery the Linux will stop the remote, load the same
firmware again and start the remote processor. As of now, coredump
callback doest not contain any useful implementation, but this can be
changed as required
