drm/i915: Revert "drm/i915/tgl: Wa_1607138340"
This reverts commit 08fff7aeddc9dd72161b4c8fc27fbab12b4b9352.
For some yet unexplained reason not having this improves stability of some
media workloads.
Promise is that the media hang will be root caused properly and in the
meantime absence of this workaround is unlikely to cause problems.
