gpu: nvgpu: set graphics specific PRI values for graphics contexts

Browse Source 
Add new HAL gops.gr.init.set_default_gfx_regs() to set graphics specific
PRI values for graphics contexts in function nvgpu_gr_obj_ctx_alloc().

Add new HAL gops.gr.init.capture_gfx_regs() to capture and save init
values for the PRIs. Add new struct nvgpu_gr_obj_ctx_gfx_regs to hold the
PRI init values.

Define HAL functions gv11b_gr_init_set_default_gfx_regs() and
gv11b_gr_init_capture_gfx_regs(). Set the HAL functions for
gv11b and ga10b.

Register accessors required to set PRIs are auto-generated.
