gpu: nvgpu: gv11b: update css ops

Updated following hal functions for css gv11b and reused
them for gv100:
enable_snapshot
disable_snapshot
check_data_available

These changes are needed because of following reasons:
1. Register offsets for perf_pmasys_* are changed
   for gv11b/gv100 from gk20a.
2. Updated memory type for perf_pmasys_mem_block_target
   based on memory aperture used for hwpm inst_block.
