0f501d806f gpu: nvgpu: Unit test fixes and staging for device rework
Fix up what unit tests can be easily fixed up. Stage everything else.

In short the unit test code is _incredibly_ fragile since it's designed
to hit every branch, positive and negative, in the code. However, the
result of that is unit tests that are painful to modify.

A lot of unit tests are also extremely opaque and rely on internal
nvgpu behavior. This patch will be updated with fixes as I make them.

Or, alternatively, it may be worth just temporarily disabling unit
tests on dev-main. We'll have a _lot_ of work for Orin that will
essentially gut the gr, host, and interrupt code. If we retain the
unit test code for this, it may end up being backgreaking.

5f0fdf085c nvgpu: unit: Add new mock register framework
Many tests used various incarnations of the mock register framework.
This was based on a dump of gv11b registers. Tests that greatly
benefitted from having generally sane register values all rely
heavily on this framework.

However, every test essentially did their own thing. This was not
efficient and has caused a some issues in cleaning up the device and
host code.

Therefore introduce a much leaner and simplified register framework.
All unit tests now automatically get a good subset of the gv11b
registers auto-populated. As part of this also populate the HAL with
a nvgpu_detect_chip() call. Many tests can now _probably_ have all
their HAL init (except dummy HAL stuff) deleted. But this does
require a few fixups here and there to set HALs to NULL where tests
expect HALs to be NULL by default.

Where necessary HALs are cleared with a memset to prevent unwanted
code from executing.

Overall, this imposes a far smaller burden on tests to initialize
their environments.

Something to consider for the future, though, is how to handle
supporting multiple chips in the unit test world.

75be2f3f2c gpu: nvgpu: unit: therm: use gops for HALs
Switch to calling the gops for the HALs rather than the HAL directly.
Update the SWUTS to reflect this change.
This allows traceability with the SWUD.
Also, move a non-fusa hal to the non-doxygen section for gops_therm.h.
