[Intel-gfx] [PATCH 19/73] drm/i915: Remove duplicate golden render state init from execlists

Mon Aug 1 09:10:27 UTC 2016
Now that we use the same vfuncs for emitting the batch buffer in both
execlists and legacy, the golden render state initialisation is
identical between both.
v2: gcc wants so.ggtt_offset initialised (even though it is not used)
