Load STM32_SIP_SVC_OK in output argument a0 on return from
SCMI message notification from SiP SMC function IDs. It simplifies
non-secure world to consider any non-zero values,
including standard unknown function error code (-1), as

plat-stm32mp1: SiP SMC service for BSEC access

Implement a SiP SMC based interface fàr the non-secure world to access
BSEC words. The service is embedded upon CFG_STM32_BSEC_SIP=y. If not
embedded, the service simply reports a failure.

This service is used by U-boot package since its release v2019.07-rc1 [1]
to retrieve information such as the device MAC address [2].

plat-stm32mp1: foundation for SCMI service

Embed a SCMI server in stm32mp1 based on SCMI message drivers.
The platform currently supports only the SCMI Base protocol.

Platform provides 2 Arm SMCCC fastcall communication channels each
using a small shared memory buffer is SYSRAM manage with a SMT header
for SCMI message exchange.

Default disable CFG_CORE_ASLR, CFG_LOCKDEP, CFG_TEE_CORE_DEBUG and
CFG_UNWIND for TEE RAM memory constraints since SCMI server with a
fastcall message processing path consumes several pages of SoC internal
SYSRAM where TEE pager resides.
