Add support for Seeed Studio's stm32mp157c odyssey board. Board consists of SoM with stm32mp157c with 4GB eMMC and 512 MB DDR3 RAM and carrier board with USB and ETH interfaces, SD card connector, wifi and BT chip AP6236. In this patch only basic kernel boot is supported and interfacing SD card and on-board eMMC.
