gpu: nvgpu: gv11b: handle l2 related changes
Implemented gv11b specific l2 state init and Configured
ltc_ltcs_ltss_cbc_num_active_ltcs_r with following info:
- cbc_num_active_ltcs is read only for gv11b, so did not
write any data to that field.
- enforced serilized access to l2 from sysmem and peermem.
- nvlink connected peer trafic sent through l2
JIRA GV11B-71
