remoteproc: core: Full attach detach during recovery

Browse source

Current attach on recovery mechanism loads the clean resource table
during recovery, but doesn't re-allocate the resources. RPMsg
communication will fail after recovery due to this. Fix this
incorrect behavior by doing the full detach and attach of remote
processor during the recovery. This will load the clean resource table
and re-allocate all the resources, which will set up correct vring
information in the resource table.
