This change implements platform services for stm32mp1 to expose clock and reset controllers over SCMI clock and reset domain protocols in sp_min firmware. Requests execution use a fastcall SMC context using a SiP function ID. The setup allows the create SCMI channels by assigning a specific SiP SMC function ID for each channel/agent identifier defined. In this change, stm32mp1 exposes a single channel and hence expects single agent at a time. The input payload in copied in secure memory before the message in passed through the SCMI server drivers. BL32/sp_min is invoked for a single SCMI message processing and always returns with a synchronous response message passed back to the caller agent. This change fixes and updates STM32_COMMON_SIP_NUM_CALLS that was previously wrongly set 4 whereas only 1 SiP SMC function ID was to be counted. STM32_COMMON_SIP_NUM_CALLS is now set to 3 since the 2 added SiP SMC function IDs for SCMI services.
