[Intel-gfx] [PATCH] drm/i915/bdw: Enable execlists by default where supported

[Thomas Daniel]

Execlist support in the i915 driver is now considered good enough for the
feature to be enabled by default on Gen8 and later and routinely tested.
Adjusted i915 parameters structure initialization to reflect this and updated
the comment in intel_sanitize_enable_execlists().
