Add STM32MP157C-DK2 support. This profile also supports the STM32MP157F-DK2 board. The only difference between these two boards is the CPU frequency (650MHz for 157C and 800MHz for 157F). A SCMI variant is available. With this variant the reset and clock resources are provided by OP-TEE and the associated SCMI services. It is the configuration recommended by STMicroelectronics, with secured system resources. The specifications bellow only list supported features.
