firmware: arm_scmi: Add helper to trace bad messages
Upon reception of malformed and unexpected timed-out SCMI messages, it is
not possible to trace those bad messages in their entirety, because usually
we cannot even retrieve the payload, or it is just not reliable.
Add a helper to trace at least the content of the header of the received
message while associating a meaningful tag and error code.
