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.

- Add test scenarios for achieving branch coverage
  for failure of dynamic memory allocation while
  preparing ucode blob.
- Add more branch coverage for nvgpu_acr_bootstrap_hs_acr()
- Move GR reg space required for ACR tests to ACR unit test
  itself to remove dependency on GR unit
