Subject: [PATCH] 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: 6cccc8d396bf ("ARM: dts: stm32: add SCMI version of STM32 boards (DK1/DK2/ED1/EV1)")
