The STM32MP157C-DK2 and STM32MP157A-DK1 are basically the same board except the DK2 has a MIPI-DSI display attached and the SoC has a crypto IP block.
Allow the same barebox image to run on both boards by deciding that if we are compiled with a 157C-DK2 device tree, but we have a 157A SoC, it must be a DK1 instead.
