gpu: nvgpu: Support GPC and FBP Floorsweeping

Browse Source 
- Add gops_fbp_fs and gops_gpc_pg struct
- Add HALs to write to NV_FUSE_CTRL_OPT_FBP and
  NV_FUSE_CTRL_OPT_GPC fuses needed for floorsweeping
- Add set_fbp_mask and set_gpc_mask to probe FBP and GPC mask
  respectively during gpu probe
- Add sysfs node: fbp_fs_mask and gpc_fs_mask to store
  FBP and GPC floorsweeping mask sent from userspace
- Move the floorsweeping programming early in NVGPU’s GPU init
  function and then issue a PRI init.
