ARM: stm32mp: add support for STM32MP157-EV1 board
The STM32MP157A-EV1 and STM32MP157C-EV1 Evaluation boards are the
full-feature demonstration and development platforms for
STMicroelectronics Arm®-based dual Cortex®-A7 32 bits and
Cortex®-M4 32 bits MPUs in the STM32MP1 Series.
Add support for running barebox as SSBL on either of them.
