Distinguish more clearly between source files meant for producing .dtb
from those meant for producing .dtbo.
In this case, the files are really meant to be compiled to .dtbo ->
.dtbo.S -> .dtbo.o that get embedded in the image, which means that
the begin/end symbols generated by the makefile rule changes to
__dtbo_ rather than __dtb, so the consuming .c file needs updating,
but this should not result in any functional change.
Note that in the linux tree, all device tree overlay sources have been
renamed to .dtso, and the .dts->.dtbo rule is gone since v6.5 (commit
81d362732bac). So this is also a step towards staying closer to linux
with respect to both Kbuild and device tree sources.

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.
In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.
This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.

This adds a bunch of unit tests for the "fdt apply" command.
They've all been run successfully in the sandbox. However, as you still
require an out-of-tree dtc with overlay support, this is disabled by
default.
