This patch fixes a bug in the cbc initialization code for ga10b,
where it was erroneously assumed that a fixed ltc count of only one
should be used for historical reasons. For volta and later, the full
ltc count should be used in cbc-related computation.
Ensure
- CBC base address is 64K aligned
- CBC start address lies within CBC allocated memory
Check CBC is marked safe only for silicon platform.

Currently, cbc init and compression tests are failing because MMU marks
cbc to be not safe.
- Modify cbc.get_base_divisor hal to use ltc_count = 1 for Tegra devices
- Update fb.cbc_configure to write compbit_backing_size value to
fb_mmu_cbc_top register.
- After config confirm that CBC is marked safe.

Replace all nvgpu_next functions/structs either by 1) collapsing them
into nvgpu legacy functions/structs 2) renaming them as follows:
- nvgpu_next_*() => nvgpu_(ga10b/ga100)_*()
- nvgpu_next_*() => (ga10b/ga100)_*()
- nvgpu_next_*() => nvgpu_*() [only if this doesn't cause collision]
- nvgpu_next_*() = > nvgpu_*_extra()
Create hal.sim unit and move Ampere+ SIM code into it.
