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.

This adds the initial unit test for the fuse module and testing for
gp10b. It verifies the exposed APIs for this device in the fuse module.
To allow the hal_init to pass before the HAL for
read_gcplex_config_fuse() can be overridden, the default behavior of the
POSIX implementation for nvgpu_tegra_fuse_read_gcplex_config_fuse() is
changed.
This provides 100% code and branch coverage for this unit/device.
