[Intel-gfx] [PATCH] Revert "drm/i915: Implement Wa_1607090982"

[Chris Wilson]

BIT(14) is not sticking in 0xe4f4 so we have no idea if the w/a is still
in effect when it needs to be. Until that is resolved, remove the
failing bit.

Closes: https://gitlab.freedesktop.org/drm/intel/issues/1169

Re: [Intel-gfx] [PATCH] Revert "drm/i915: Implement Wa_1607090982"

[Matt Roper]

The headline for the patch you're reverting was somewhat confusing since
it doesn't match the name used in the code comment below or the bspec
workaround page (Wa_1606931601).  But it looks like both numbers refer
to the same workaround in the underlying database, so it's the correct
revert.

Maybe also add a reference to the preferred Wa_1606931601 name in your
commit message so that it's easier to find when searching git history?
That might help prevent someone from accidentally re-implementing this
workaround the next time we scrub the WA database.
