[PATCH v7 13/16] firmware: arm_scmi: Add new parameter to mark_txdone

Add a new xfer parameter to mark_txdone transport operation which enables
the SCMI core to optionally pass back into the transport layer a reference
to the xfer descriptor that is being handled.

v6 --> v7
- use __unused macro for new param in existing transports
