The SCMI transport layer communicates via mailboxes and shared memory with firmware running on a microcontroller. It is platform specific how long it takes to pass a SCMI message. The most sensitive requests are coming from CPUFreq subsystem, which might be used by the scheduler. Thus, there is a need to measure these delays and capture anomalies. This change introduces trace events wrapped around transfer code. According to Jim's suggestion a unique transfer_id is to distinguish similar entries which might have the same message id, protocol id and sequence. This is a case then there are some timeouts in transfers.
