drivers/scmi-msg: support for clock protocol Adds SCMI clock protocol support in the SCMI message drivers as defined in SCMI specification v2.0 [1] for clock protocol messages. Platform can provide one of the plat_scmi_clock_*() handler for the supported operations set/get state/rate and others. scmi_msg_get_clock_handler() sanitizes the message_id value against any speculative use of clock ID as a index since by SCMI specification, IDs are indices. This implementation is based on the OP-TEE project implementation [2] itself based on the SCP-firmware implementation [3] of the SCMI protocol server side.
