This change implements SCMI channels for reading a SCMI message from a
shared memory and call the SCMI message drivers to route the message
to the target platform services.
SMT refers to the shared memory management protocol which is used
to get/put message/response in shared memory. SMT is a 28byte header
stating shared memory state and exchanged protocol data.
The processing entry for a SCMI message can be a secure interrupt
(CFG_SCMI_MSG_SMT_INTERRUPT_ENTRY=y), and fastcall SMC
(CFG_SCMI_MSG_SMT_FASTCALL_ENTRY=y) or a threaded execution
context entry (CFG_SCMI_MSG_SMT_THREAD_ENTRY=y).
SMT description in this implementation is based on the SCP-firmware
implementation [1].
