Subject: [PATCH v3 6/9] include: trace: Add SCMI FastChannel tracing
All the currently defined SCMI events are meant to trace only regular SCMI
transfers based on SCMI messages exchanges; SCMI transactions based on
FastChannels, where used, are completely invisible from the tracing point
of view.
Add support to trace FastChannel transactions; while doing that avoid
exposing full shared memory location addresses.
