firmware: arm_scmi: Add polling support to raw mode

2025-04-14T09:12:13Z

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.
