Provide a couple of additional debugfs entries to enable polling-mode on
the waiting path of injected messages: message_poll will cause the system
to poll while waiting for the reply, while message_poll_async will send an
asynchronous message, as usual, and will use polling mode for the immediate
synchronous part of the async command.

which transport channel to use for the SCMI message injection.
