[Intel-gfx] [PATCH 30/31] drm/i915: Support secure dispatch on gen6/gen7

[Chris Wilson]

Re-enable secure dispatch for gen6/gen7, primarily to workaround the
command parser and overly zealous command validation on Haswell. For
example this prevents making accurate measurements using a journal for
store results from the GPU without CPU intervention.
