arm: dts: sl28: sync dtbs

Copy the board device tree files from linux v5.14. On top of the v5.14
dtbs the changes of these two patches are included here which are needed
for u-boot:
  https://lore.kernel.org/linux-devicetree/20210831134013.1625527-7-michael@walle.cc/
  https://lore.kernel.org/linux-devicetree/20210831134013.1625527-8-michael@walle.cc/

At the time of this writing the patches were accepted and will be
included in 5.15.
