ea5a4d69d8 ARM: dts: stm32: Fix reset for usart1 in scmi configuration 
In SCMI configuration, usart1 is secure, so all its resources are secured
(clock and reset) and can't be set/unset by non-secure world but by OP-TEE.

Fixes: 6cccc8d396 ("ARM: dts: stm32: add SCMI version of STM32 boards (DK1/DK2/ED1/EV1)")

Now that Linux has accepted these tags, move the device tree files in
U-Boot over to use them.

6cccc8d396 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.
