[Nouveau] [PATCH v5 0/18] Secure Boot refactoring

[Alexandre Courbot]

Sending things in a smaller chunks since it makes their reviewing
easier.

This part part 2/3 of the secboot refactoring/PMU command support
patch series. Part 1 was the new falcon library which should be
merged soon now.

This series is mainly a refactoring/sanitization of the existing
secure boot code. It does not add new features (part 3 will).

Secure boot handling is now separated by NVIDIA firmware versions,
and LS firmwares are also loaded and managed in their own source
files. This makes the code easier to understand (more bite-size
chunks instead of thousands of LoC source files) and extend since
the proper abstractions are now in place.

The next big chunk will be PMU commands handling. Since PMU is not
the only falcon that will have to manage commands (SEC2 will manage
security features in newer firmwares), I am currently rewriting it
as part of the falcon library instead of the PMU subdev. This will
make things more reusable and will allow us to close the loop with
the current falcon engine code - please just allow me a few more days
to finish this! :)

In the meantime, this code should be good to go and test.
