For tests, we need some example dtbs that are generated without using dtc
or libfdt. This is for two reasons:
* We want to check exact byte-for-byte properties independently of the
main code - we don't want bugs in one to mask bugs in the other
* We need to generate some deliberately malformed trees to test error
handling
Currently, these are generated (somewhat oddly) using the assembler -
we use assembler macros in trees.S which constructs them "in memory", then
dumptrees.c links against that and dumps them out as files. This is
arguably an abuse of the assembler, and it's fairly fragile. Platforms
with unusual symbol naming conventions can cause it to break, and some
assembler versions (e.g. the one on MacOS) don't work with it.
This replaces it with a bespoke C code, with a structure to at least
somewhat maintain the readability of the examples. Output is byte for
byte identical with the previous version. For now we add tests that check
the new code generates (byte for byte) identical output, but still use
the old version in our other tests.
