gpu: nvgpu: gv11b: fix for gfx preemption
Used chip specific attrib_cb_gfxp_default_size and
attrib_cb_gfxp_size buffer sizes during committing
global callback buffer when gfx preemption is requested.
These sizes are different for gv11b from gp10b.
Also used gv11b specific preemption related functions:
gr_gv11b_set_ctxsw_preemption_mode
gr_gv11b_update_ctxsw_preemption_mode
This is required because preemption related buffer
sizes are different for gv11b from gp10b. More optimization
will be done as part of NVGPU-484.
Another issue fixed is: gpu va for preemption buffers
still needs to be 8 bit aligned, even though 49 bits
available now. This done because of legacy implementation
of fecs ucode.
