Add a "secure" version of STM32 boards based on SCMI when RCC_TZCR.TZEN=1. Only boards provided by STMicroelectronics are concerned: -STM32MP157A-DK1 -STM32MP157C-DK2 -STM32MP157C-ED1 -STM32MP157C-EV1 The resources secured by RCC_TZCR.TZEN=1 are managed by OP-TEE and the associated SCMI services, reset and clock. These device trees are only supported with stm32mp15_defconfig, with OP-TEE, SCMI and without SPL support.
