drm/i915/gt: Fixup tgl mocs for PTE tracking
commit be33805c65297611971003d72e7f9235e23ec84d upstream.
Forcing mocs:1 [used for our winsys follows-pte mode] to be cached
caused display glitches. Though it is documented as deprecated (and so
likely behaves as uncached) use the follow-pte bit and force it out of
L3 cache.
