gpu: nvgpu: ga10b: Use active ltcs count for cbc init

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.
