gpu: nvgpu: units: pramin build issues for dGPU
...
Fix pramin related build issues in unit tests, when enabling dGPU
in safety build.
pram_data032_r is now defined as a macro which cannot be used to
initialize g->ops.pramin.data032_r in unit tests.
Instead, use nvgpu_pramin_ops_init, and check that
g->ops.pramin.data032_r is non NULL.

gpu: nvgpu: build flag for compression_page_size
...
Use CONFIG_NVGPU_COMPRESSION flag instead of CONFIG_NVGPU_DGPU
for g->ops.fb.compression_page_size.
This is to allow compiling dGPU without compression in safety build.

gpu: nvgpu: mm: limit recursion depth for pd levels
...
The two MM functions nvgpu_set_pd_level() and nvgpu_vm_do_free_entries()
are simple recursive functions for processing page descriptors (PDs) by
traversing the levels in the PDs. MISRA Rule 17.2 prohibits functions
calling themselves because "unless recursion is tightly controlled, it
is not possible to determine before execution what the worst-case stack
usage could be." So, this change limits the recursion depth of each of
these functions to the maximum number of page table levels by checking
the level against the MM HAL max_page_table_levels().
This also required configuring this HAL in various unit tests as they
were no previously using this HAL.
