drm/i915/vlv:Implement the WA 'WaDisable_RenderCache_OperationalFlush'
On Gen4+ platforms (except BDW), Render Cache Operational flush
cannot be enabled.
This WA is apparently required for all Gen4+ platforms,except BDW.
In BDW, the bit has been repurposed otherwise.
This has been tested only on vlv.
v2: Corrected the code regarding the wrong usage of
MASKED_BIT_DISABLE (Chris)
v3: Enhancing the scope of WA to Gen4+ platforms except BDW (Ville)
v4: Adding WA for g4x, crestline, broadwater (Ville)
