Separated set_atomic_mode functionality from init_fs_state/enable_nvlink and created new fb gops for set_atomic_mode. In gpu init sequence, set_atomic_mode is called after acr_construct_execute to take care of design changes required for nvgpu-next architectures. Updated fb_gv11b_init_test to use set_atomic_mode gops along with init_fs_state.
