gpu: nvgpu: remove VPR HALs from dGPUs

gops.fb.dump_vpr_wpr_info() accesses both VPR and WPR registers.
Split this into two different HALs gops.fb.dump_vpr_info() and
gops.fb.dump_wpr_info()

Also unset HALs accessing VPR registers on dGPUs
We don't support VPR on dGPUs

Remove fb_mmu_vpr_info_r() register and all its accessors from
dGPU headers
