ARM: dts: stm32: add SCMI version of STM32 boards (DK1/DK2/ED1/EV1)
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.
