Moved cbc related code and data from gr to cbc unit. Ltc and cbc related data is moved from gr header: 1. Ltc related data moved from gr_gk20a -> gk20a and it will be moved eventually to ltc unit: u32 slices_per_ltc; u32 cacheline_size; 2. cbc data moved from gr_gk20a -> nvgpu_cbc u32 compbit_backing_size; u32 comptags_per_cacheline; u32 gobs_per_comptagline_per_slice; u32 max_comptag_lines; struct gk20a_comptag_allocator comp_tags; struct compbit_store_desc compbit_store; 3. Following config data moved gr_gk20a -> gk20a u32 comptag_mem_deduct; u32 max_comptag_mem; These are part of initial config which should be available during nvgpu_probe. So it can't be moved to nvgpu_cbc. Modified code to use above updated data structures. Removed cbc init sequence from gr and added in common cbc unit. This sequence is getting called from common nvgpu init code.
