Subject: drm/i915/gt: Set unused mocs entry to follow PTE on tgl as on all
Git-commit: 93975d613ec0731ce3148b543cbf675b3251bfff

Be consistent in our mocs setup on Tigerlake and set the unused control
value to follow the PTE entry as we previously have done. The unused
values are beyond the defines of the ABI, the consistency simplifies our
checking.
