fdt: Show a runtime warning based on devicetree sourceWIP/2021-12-13-make-OF_BOARD-a-boolean
When running, if the devicetree failed to come from the expected source,
show a warning, e.g:
U-Boot ...
DRAM: 128 MiB
Core: 42 devices, 11 uclasses, devicetree: separate
Warning: Unexpected devicetree source (not from a prior stage)
Warning: U-Boot may not function properly
Flash: 64 MiB
...
These warnings should only appear if the board config has been changed, or
the prior stage is broken.
