Chris Wilson 972745fd57 drm/i915/gt: Disable manual rc6 for Braswell/Baytrail 
The initial investigated showed that while the PCU on Braswell/Baytrail
controlled RC6 itself. setting the software RC6 request made no
difference. Further testing reveals though that it causes a delay in the
PCU on enabling RC6.
