include: trace: Add SCMI fast channel tracing
All the currently defined SCMI events are meant to trace only regular SCMI
transfers based on SCMI messages exchanges; SCMI transactions based on
fast channels, where used, are completely invisible from the tracing point
of view.
Add support to trace fast channel transactions; while doing that avoid
exposing full shared memory location addresses.
