ARM SCMI updates for v5.6

1. Addition of multiple device support per protocol to enable use of
   some procotols by multiple kernel subsystems simultaneously and
   corresponding updates to the existing scmi drivers
2. Addition of trace events around the scmi transfer code to measure
   any delays and capture anomalies that can also be used during
   investigation of some platform firmware related issues
