ARM: dts: stm32: Synchronize DT with kernel one
This patch synchronizes U-boot DT with kernel one This is based on https://patchwork.kernel.org/cover/10797115/ This patch adds initial support of STM32MP157 discovery boards: - Add support of stm32mp157a discovery1 board (part number: STM32MP157A-DK1). This board embeds a STM32MP157a SOC with AC package (TFBGA361, 148 ios) and 512MB of DDR3. Several connections are available on this boards: 4*USB2.0, 1*USB2.0 typeC, SDcard, RJ45, HDMI, Arduino connector, ... - Add support of stm32mp157c discovery2 board (part number: STM32MP157C-DK2). This board is a "super-set" of stm32mp157a-dk1. A display panel (otm8009a) and Murata wifi/BT combo is added.
