remoteproc: Change rproc_shutdown() to return a status
The rproc_shutdown() function is currently not returning any
error code, and any failures within rproc_stop() are not passed
back to the users. Change the signature to return a success value
back to the callers.
The remoteproc sysfs and cdev interfaces are also updated to
return back this status to userspace.
