drm/i915: Fix GT_MODE default value

commit f8f2ac9a76b0f80a6763ca316116a7bab8486997 upstream.

I can't even find how I figured this might be needed anymore. But sure
enough, the value I'm reading back on platforms doesn't match what the
docs recommends.

It seemed to fix Chris' GT1 in limited testing as well.
