[Intel-gfx] [PATCH v2 9/9] drm/i915: Enable atomic by default on ctg/elk

[Ville Syrjala <ville.syrjala@linux.intel.com>]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

The watermark code for ctg/elk has been atomic ready for a long time
so let's just flip the switch now that some of the last CxSR issues
have been sorted out (which granted was a problem for vlv/chv as well
despite them already having atomic enabled by default).
