dt-bindings: firmware: arm,scmi: Add support for notification completion channel

Per System Control Management Interface specification:
"Completion interrupts: This transport supports polling or interrupt driven
 modes of communication. In interrupt mode, when the callee completes
 processing a message, it raises an interrupt to the caller. Hardware
 support for completion interrupts is optional."

So, add an optional mailbox channel for notification completion interrupts.
