gpu: nvgpu: expose physical masks for GPCS/FBPs for MIG

Browse Source 
Following changes are added
1) nvgpu_gr_config->gpc_tpc_mask_physical is now indexed by physical
gpc id instead of logical id.
2) Removed the conversion of logical fbp ids and replace them with
physical ids.
3) nvgpu_gpu_instance->fbp_en_mask now contains the mask of physical fbp ids.
4) gk20a_ctrl_ioctl_gpu_characteristics returns gpu.gpc_mask returns mask
of physical ids.
