remoteproc: xlnx: Release mailbox channels on shutdown

Mailbox driver can't introduce shutdown callback, as it might endup
closing mbox channels prematurely. By allowing the client driver to
manage the shutdown process, it's ensured that mailbox channels are
closed only when they are no longer needed.
