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.
