gpu: nvgpu: initialize czf_bypass only once
We right now initialize czf_bypass value in gr_gp10b_init_preemption_state()
which is run at every rail ungate
And that results in any user specified value through sysfs getting lost after
railgate
To fix this, move initialization of czf_bypass to gk20a_init_gr_setup_sw() so
that it gets initialized only once
Add new HAL g->ops.gr.init_czf_bypass to initialize same and define it for
gp10b/gp106/vgpu-gp10b
