gpu: nvgpu: report gpc_tpc_mask in physical order

Browse Source 
At present, there is an inconsistency in the order in which
gpc_tpc masks are reported to the userspace. Both gpc and
tpc masks are reported using physical-ids. However, the
gpc_tpc_masks array is ordered by logical gpc-ids and
not physical-ids. This creates a mismatch between the gpc
reported as enabled in the gpc_mask and its corresponding
gpc_tpc_mask.

Introduce field "gpc_tpc_mask_physical" which stores the
gpc_tpc_masks in physical order and update
NVGPU_GPU_IOCTL_GET_TPC_MASKS to return this field.
