gpu: nvgpu: ga10b: update PMM litter values

Browse Source 
Fix PMM litter values for ROP and LTC units.

The ROP unit has been moved from FBP to GPC, hence, introduce new litter
constants:
- GPU_LIT_PERFMON_PMMGPC_ROP_DOMAIN_START
- GPU_LIT_PERFMON_PMMGPC_ROP_DOMAIN_COUNT
Previous PMMFBP_ROP litter constants are removed.

Update GPU_LIT_PERFMON_PMMFBP_LTC_DOMAIN_COUNT to 4.

Jira NVGPU-7204
