Since OP-TEE commit 89ba3422ee80 ("plat-stm32mp1: scmi_server: default use OP-TEE shared memory"), integrated in OP-TEE 3.22.0-rc1 the default configuration for STM32MP15x SoCs changes, CFG_STM32MP1_SCMI_SHM_SYSRAM is disabled by default and the OP-TEE SMCI server uses ithe OP-TEE native shared memory registered by clients.
To be compatible by default with this configuration and the next OP-TEE version, this patch removes the SHMEM in the SCMI configuration and the associated reserved memory in the last 4KByte page of SRAM, in the STM32MP15 device tree.
