Merge patch series "Add Turris 1.x board"

Hello all,

this is a continuation of previous work by Pali to add support for the
Turris 1.x board. As the patches were based on u-boot v2022.04, a
nontrivial rebasing was needed.

Some notes:
- Some options that are in SD defconfig are disabled in NOR defconfig
  because over the years u-boot grew and the old NOR defconfig will not
  fit into NOR memory.
- SD boot with RAM larger than 2GB will only allocate 2GB of RAM (We
  were not able to fix this yet)
