gpu: nvgpu: add fb gops for set_atomic_mode

Browse Source 
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.

Bug 3268664
