Hi,
New summary when compared to v2:
* Patches 1 and 2 are just cleanup
* Patch 3 is a modification of the CODING_STYLE to reflect the unwritten rule
of splitting type names in words.
* Patch 4 is a rename of struct bootmodule{,s} to boot_module{,s}, in
accordance
to the modification of patch 3.
* Patch 5-7 replaces x86-specific boot_{domain,module} defs in favour of
common ones.
* The rest are code motion and enablement of x86 to unflatten DTs and use
some dom0less helpers.

It's a first round of cleanup and preparation to have a much easier time
later when integrating dom0less boot into hyperlaunch.
The refactor on device-tree/ is _fine_ by I'm open to other suggestions
to achieve the same thing. In particular, after this series x86 can
unflatten the DT host device tree when it has CONFIG_DOM0LESS_BOOT set,
which enables the builder to use factored-out functions from
dom0less-build.c (not done here).
The diffstat is deceptive because I renamed a large file and then
created a new file with the same name. There aren't that many LoC
changes.
