On some systems the SCMI platform to agent(p2a) communication can be fully interrupt driven. The notification(p2a) channel needs completion interrupt to drive its notification queue at the platform. Without it, the platform notification will not work as the platform will wait for agent indication of clearing the channel via interrupt unlike few platforms which can poll instead. To support such systems, an optional unidirectional mailbox channel for p2a reply communication. If the platform sets channel INTR flag set indicating that it expects the agent to trigger the interrupt to acknowledge the reciept of the notification or any p2a message, and the completion interrupt channel is provided, send a mailbox message to the platform after the p2a message is read and channel is freed to accept new notifications or p2a messages.
