[Intel-gfx] [PATCH v10 7/7] drm/i915: Enable GuC TLB invalidations for MTL

Enable GuC TLB invalidations for MTL.  Though more platforms than just
MTL support GuC TLB invalidations, MTL is presently the only platform
that requires it for any purpose, so only enable it there for now to
minimize cross-platform impact.
