[PATCH 01/18] drm/i915: Mark per-engine-reset as supported on gen6+

The benefit of only reseting a single engine is that we leave other
streams of userspace work intact across a hang; vital for process
isolation. We had wired up individual engine resets for gen6, but only
enabled it from gen8; now let's turn it on for the forgotten.
