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.
