Vedashree Vidwans a7a2e1e263 gpu: nvgpu: ga10b: update cbc divisor and top reg ...

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.
